Event monitor: Overview, Uses and Top Manufacturer Company

Introduction

Event monitor is a category of ambulatory (out-of-hospital) electrocardiogram (ECG) recording medical equipment designed to capture intermittent heart rhythm abnormalities (arrhythmias), especially when symptoms are infrequent and a short continuous recording may miss the event. In practical terms, it helps clinicians connect “what the patient felt” (palpitations, dizziness, near-syncope) with “what the heart was doing” at that moment.

In hospitals and clinics, Event monitor workflows sit at the intersection of clinical decision-making, patient education, device logistics, data management, and safety. Unlike bedside telemetry, many Event monitor pathways rely on the patient to wear the device correctly, trigger recordings, and transmit data—making human factors, training, and follow-up essential.

This article explains what Event monitor is, when it is commonly used (and when alternatives may be preferred), how it generally works, and how to operate it safely. It also covers troubleshooting, infection prevention considerations, and operational requirements for commissioning and maintaining this clinical device in real-world health systems. Finally, it provides a non-numerical, globally aware market snapshot and an overview of manufacturers, OEM relationships, and distribution channels relevant to procurement and hospital operations.

What is Event monitor and why do we use it?

Event monitor is a non-implantable ambulatory ECG recording device used to detect transient or intermittent arrhythmias over an extended period. The defining feature is that ECG segments are recorded when an “event” occurs—either because the patient activates the recording during symptoms, or because the device’s algorithm automatically detects a rhythm change and stores the relevant ECG strip. The stored recordings are then reviewed by trained clinicians, often within a cardiology service line.

What problem does it solve?

Many rhythm problems are episodic. A standard 12‑lead ECG provides a short snapshot, and a 24–48 hour Holter monitor provides continuous recording over a limited window. Event monitor extends the monitoring horizon and focuses data capture around clinically meaningful moments, improving the chance of documenting a rhythm during infrequent symptoms.

Common clinical settings

Event monitor is commonly deployed across:

• Outpatient cardiology and internal medicine clinics evaluating intermittent symptoms.
• Emergency department discharge pathways when immediate life-threatening causes have been excluded and longer rhythm correlation is needed per local protocols.
• Post-procedure or post-medication change follow-up (for example, when monitoring for recurrence of certain arrhythmias), where appropriate and defined by the treating team.
• Rural and community settings where advanced in-hospital rhythm monitoring is limited, and ambulatory monitoring helps reduce unnecessary repeat visits.

Key benefits for patient care and workflow

From a clinical perspective, Event monitor can:

• Improve symptom–rhythm correlation when symptoms are sporadic.
• Reduce “diagnostic uncertainty” by capturing real ECG tracings rather than relying only on patient description.
• Support triage decisions about further testing or specialist follow-up (as determined by clinicians).

From an operational perspective, it can:

• Shift monitoring from inpatient beds to ambulatory pathways when clinically appropriate.
• Create a structured data pipeline (device → transmission → over-read → report) that is measurable and auditable.
• Enable standardized follow-up workflows, which can reduce missed results when governance is strong.

Plain-language mechanism of action (how it works)

Most Event monitor systems include:

• Sensors/electrodes attached to the skin to detect the heart’s electrical signals.
• A recorder (small wearable device or patch-based unit) that converts signals into ECG tracings.
• A memory buffer (often a “loop”) that continuously holds a short rolling segment so the device can store a window before and after the event.
• A trigger mechanism:
• Patient-activated: the patient presses a button during symptoms.
• Auto-triggered: algorithms detect patterns such as pauses, very fast/slow rates, or irregular rhythms (capabilities vary by manufacturer).
• A transmission pathway (varies by model): docking station, smartphone app, cellular hub, or manual download in clinic.

Event monitor outputs are typically short rhythm strips with timestamps and sometimes symptom tags, rather than full multi-lead diagnostic ECGs. This is an important limitation and an important reason to interpret results in clinical context.

How medical students encounter this device in training

Medical students and trainees typically learn about Event monitor during:

• Teaching on syncope, palpitations, and arrhythmia evaluation (preclinical cardiology blocks and clinical rotations).
• Cardiology clinic placements where ambulatory ECG options are compared (12‑lead ECG vs Holter vs Event monitor vs implantable cardiac monitor).
• Hospital operations exposure (handoffs, discharge planning, outpatient diagnostics) where follow-through and patient adherence are emphasized.
• ECG interpretation teaching sessions that highlight artifacts, lead placement issues, and algorithm limitations in ambulatory monitoring.

For learners, Event monitor is a useful case study in how a medical device, patient behavior, and service design combine to produce (or undermine) diagnostic value.

When should I use Event monitor (and when should I not)?

Selection of Event monitor is a clinical decision that should follow local protocols and supervision requirements. The points below describe common patterns of use and non-use for general education, not individualized care.

Appropriate use cases (common patterns)

Clinicians commonly consider Event monitor when:

• Symptoms are intermittent and may not occur during a short monitoring window.
• There is a need to correlate patient-reported symptoms with a contemporaneous ECG tracing.
• The expected diagnostic yield of continuous short-term monitoring is limited due to symptom frequency.
• The patient can reasonably participate in the process (wearing the device, pressing a button if required, and following transmission instructions).

In many systems, Event monitor is positioned between short snapshot testing (12‑lead ECG) and more intensive monitoring options, balancing diagnostic reach with patient burden and resource use.

When it may not be suitable (consider alternatives)

Event monitor may be less suitable when:

• The patient’s symptoms suggest an acute emergency requiring immediate evaluation and real-time monitoring rather than delayed review.
• Symptoms are very frequent or continuous, where continuous monitoring approaches may be more efficient.
• The patient is unlikely to operate the device reliably due to cognitive impairment, severe frailty, or barriers to follow-up, unless caregiver support and robust workflows are in place.
• Skin integrity is poor or there is a history of significant skin reactions to adhesives (risk varies by manufacturer and electrode type).
• The clinical question requires more comprehensive data than the device can provide (for example, multi-lead morphology detail), depending on local practice.

Safety cautions and general contraindication themes

Contraindications and warnings vary by manufacturer and local policy. Common safety themes include:

• Skin reactions: irritation, contact dermatitis, or pressure injury from adhesives or straps.
• Electrical safety: use only approved power supplies/chargers; inspect for damaged cables; follow facility biomedical engineering guidance for electrical safety testing.
• Water exposure: many systems have limits on bathing/swimming; water resistance varies by manufacturer.
• Electromagnetic interference (EMI): certain environments or devices may introduce noise; policies vary by manufacturer and facility.
• Imaging and procedures: removal requirements around MRI, diathermy, or other procedures vary by manufacturer and device type.

Clinical governance reminder

Event monitor is typically part of a broader diagnostic pathway that includes triage, timely review, patient communication, and documentation. The device is only as effective as the system around it—especially result follow-up and escalation policies. Use should be aligned with clinical oversight, local protocols, and the manufacturer’s Instructions for Use (IFU).

What do I need before starting?

Safe and effective use of Event monitor requires preparation across people, process, and equipment. Hospitals that treat Event monitor as “just a small gadget” often encounter avoidable failures: unreadable traces, lost devices, delayed results, or preventable skin injuries.

Required setup, environment, and accessories

Common prerequisites include:

• Recorder unit and any required leads, patch, or cable set (model-dependent).
• Disposable electrodes/adhesives compatible with the recorder (consumables are often a major cost and supply-chain driver).
• Skin prep supplies (for example, alcohol wipes) as permitted by facility policy.
• Batteries/charging equipment and verified access to the correct power supply.
• Transmission method: phone-based hub, docking station, or clinic download workflow (varies by manufacturer).
• Patient instructions in appropriate languages and reading level, ideally with pictures.
• Patient diary/log (paper or app-based), if used in your workflow.

Environmental considerations:

• A clean area for application with privacy for chest lead placement.
• A designated clean storage space and a separate area for used/soiled returns awaiting cleaning.
• Reliable connectivity (cellular/Wi‑Fi) if the model transmits remotely; if not available, plan for in-person downloads.

Training and competency expectations

Competency should cover more than “stick on electrodes”:

• Correct skin preparation and electrode placement to reduce artifact.
• Confirming signal quality before the patient leaves.
• Teaching the patient how to trigger events (if patient-activated) and how to recognize and respond to device prompts.
• Clear explanation of what to do if symptoms worsen, based on facility policy and discharge instructions.
• Basic troubleshooting (electrode replacement, charging, transmission steps).
• Documentation requirements and privacy practices.

Facilities often assign this training to nursing staff, ECG technicians, or ambulatory clinic teams, with biomedical engineering and IT supporting device integrity and connectivity.

Pre-use checks and documentation

A practical pre-use checklist commonly includes:

• Verify the clinical order and intended monitoring duration per local protocol.
• Confirm patient identity and correct device assignment (serial number/asset tag linkage).
• Inspect the medical device for damage (cracks, cable strain, corrosion, loose connectors).
• Confirm battery status and clock/time synchronization if applicable.
• Confirm electrode expiry and packaging integrity.
• Perform a signal quality check after application (baseline stability, clear QRS complexes).
• Document start time, configuration (as applicable), and patient education provided.
• Confirm how/when data will be reviewed and how results will be communicated.

Operational prerequisites: commissioning, maintenance readiness, consumables, and policies

For hospitals and procurement teams, “ready to use” requires upstream work:

• Commissioning: incoming inspection, asset registration, and electrical safety testing per biomedical engineering policy.
• Preventive maintenance schedules (even if minimal): physical inspection, functional checks, battery health assessment, and software/firmware version control.
• Consumables planning: electrode types, lead replacements, adhesive availability, and waste management.
• Data governance: retention period, access control, audit trails, and a defined process for handling patient-identifiable information.
• Cybersecurity (if connected): password policies, software updates, and vendor risk review (varies by manufacturer and region).
• Service model decisions: in-house reading vs outsourced over-read services; turnaround time expectations; escalation workflows.

Roles and responsibilities (clinician vs biomedical engineering vs procurement)

Clear role boundaries reduce safety risk:

• Clinicians: define indications, order the test, interpret results (or supervise interpretation), and act on findings per protocol.
• Nursing/ECG technicians/clinic staff: apply the device, educate the patient, perform initial signal checks, and coordinate follow-up.
• Biomedical engineering: asset management, safety testing, repairs, preventive maintenance, and IFU-compliant cleaning guidance for reusable components.
• IT/informatics: connectivity, device-to-platform integration, identity management, and incident response for data issues.
• Procurement/supply chain: contracting, consumables sourcing, vendor performance monitoring, and ensuring total cost of ownership is understood (device + accessories + software + service).

How do I use it correctly (basic operation)?

Workflows vary by manufacturer and care setting, but most Event monitor pathways share a common structure: prepare the patient and skin, apply the device correctly, validate signal quality, instruct the patient, capture and transmit events, and close the loop with retrieval, cleaning, and reporting.

Basic step-by-step workflow (common, model-agnostic)

1. Confirm the order and purpose
   Verify the clinical question and monitoring duration as documented by the care team.

2. Identify the patient and explain the process
   Use facility-approved identity checks and provide a brief explanation of what the Event monitor does and what participation is required.

3. Screen for practical barriers
   Check for skin issues, adhesive sensitivity history, and whether the patient can manage charging/transmission steps. Escalate to the supervising clinician if concerns arise.

4. Prepare the skin
   Follow facility policy for cleaning and drying the skin. Good preparation reduces motion artifact and electrode detachment.

5. Apply electrodes/patch and connect the recorder
   Place electrodes according to the manufacturer diagram. Secure cables to reduce tugging. If using a patch-based system, align placement carefully.

6. Power on and verify signal quality
   Confirm the device is recording and the displayed/printed test strip (if available) is interpretable. Address artifact before the patient leaves.

7. Configure event capture settings (if applicable)
   Some models allow adjustment of recording windows (pre-/post-event duration) or auto-detection parameters. Use only settings supported by local protocol and competency.

8. Teach the patient how to capture events
   – Show how to press the event button (for patient-activated systems).
   – Explain symptom logging (diary or app).
   – Demonstrate indicator lights/alerts and what they generally mean.

9. Confirm transmission plan
   Ensure the patient knows how recordings are sent (automatic vs manual) and what to do if transmission fails.

10. Document and schedule follow-up
    Record device ID, start time, and education provided. Provide instructions for return/retrieval and who to contact for device issues.

Typical settings and what they generally mean

Not all Event monitor models expose configurable settings to users. When settings exist, they often relate to:

• Recording window: how many seconds/minutes are stored before and after an event trigger.
• Auto-detection rules: thresholds for rate extremes or rhythm irregularity detection (capabilities vary by manufacturer).
• Lead configuration: single-lead vs multi-lead collection, depending on the system.
• Signal gain/filtering: processing that can improve readability but may distort certain features if misused.

Operational principle: settings should prioritize reliable capture and interpretability, and should be standardized across the service when possible to reduce variability and training burden.

Universal good practices across models

• Validate signal quality before discharge from the clinic.
• Reinforce electrode replacement and skin care instructions when applicable.
• Use clear, language-appropriate patient education materials.
• Provide a realistic escalation pathway for device problems (clinic number, service desk, or vendor support line as defined locally).
• Plan for device return logistics; “lost to follow-up” is a predictable operational risk.

How do I keep the patient safe?

Patient safety with Event monitor extends beyond arrhythmia detection. It includes skin safety, electrical safety, data safety, and reliable clinical follow-up. Because Event monitor often leaves the controlled hospital environment, risk controls must be engineered into education, labeling, and workflows.

Physical safety and skin integrity

Common risk controls include:

• Choose electrode/adhesive types appropriate for local formulary and patient population needs (sensitivity considerations vary by manufacturer).
• Avoid excessive tension on leads; secure cables to reduce traction and skin blistering.
• Encourage routine skin checks by the patient or caregiver, with clear instructions on what to do if irritation occurs (per facility guidance).
• Consider fall and entanglement risk for patients with mobility issues; route cables to minimize snag hazards.

Electrical safety and device integrity

Event monitor is generally low power, but standard medical equipment safety practices still apply:

• Use only manufacturer-approved chargers, batteries, and accessories.
• Remove from use if the casing is cracked, connectors are loose, or cables are frayed.
• Follow biomedical engineering policies for electrical safety testing and maintenance intervals.
• Store devices to prevent crushing, fluid ingress, or extreme temperatures.

Alarm handling, notifications, and human factors

Some Event monitor systems generate prompts, alerts, or transmission reminders. Safety issues often arise when:

• Patients misunderstand what the alert means.
• Staff assume alarms are automatically escalated to clinicians.
• Alert fatigue results in delayed review.

Mitigations:

• Define who monitors transmissions and what “urgent” means within your service.
• Use scripted patient education: what to do for device alerts vs what to do for severe symptoms (as per local policy).
• Audit turnaround times and closed-loop communication (result reviewed, action documented, patient informed).

Data privacy, cybersecurity, and consent-aware workflows

Many Event monitor pathways create digital health data that may be transmitted off-site for storage or analysis. Good governance includes:

• Confirming patient identity at setup to prevent misattribution of recordings.
• Minimizing unnecessary identifiers in workflows where feasible.
• Role-based access controls and audit trails for staff accessing recordings.
• Vendor and platform security review processes (varies by manufacturer and country).
• Clear documentation of what data is collected and how it is used, aligned with local consent and privacy frameworks.

Labeling checks and a culture of incident reporting

Safety is strengthened when teams treat device issues as reportable learning opportunities:

• Verify labels, model numbers, and accessory compatibility before use.
• Encourage reporting of near-misses (wrong device assigned, unreadable traces due to setup errors, delayed review).
• Use local incident reporting systems and biomedical engineering workflows for investigation and corrective actions.
• Preserve relevant device data and logs when investigating a potential device-related event, per policy.

How do I interpret the output?

Event monitor interpretation is usually a clinician responsibility and requires ECG literacy, awareness of device limitations, and clinical correlation. Outputs can look deceptively definitive, especially when algorithm labels are present; trainees should learn to trust the tracing more than the label.

Types of outputs/readings you may see

Depending on the system, Event monitor outputs may include:

• Single-lead or limited-lead ECG strips with timestamps.
• Patient-triggered event markers linked to diary entries (symptoms, activity).
• Auto-detected events flagged by the device algorithm (features vary by manufacturer).
• Transmission logs showing when data was sent and received.
• Summary reports compiled by software platforms, sometimes with rhythm classification suggestions.

How clinicians typically interpret them (high-level approach)

Interpretation commonly follows a structured pattern:

• Confirm the strip is technically adequate (signal quality, minimal artifact).
• Identify the rhythm: rate, regularity, QRS width, and presence/relationship of P waves where visible.
• Look for clinically relevant patterns: ectopy, pauses, irregularly irregular rhythms, sustained tachyarrhythmias, or bradyarrhythmias (as defined by clinical context and protocols).
• Correlate timing with symptoms and activity log.
• Decide whether additional evaluation is required, guided by local pathways and supervision.

Common pitfalls and limitations

Event monitor has predictable limitations that should be taught explicitly:

• Artifact mimicking arrhythmia: motion, loose electrodes, muscle tremor, and cable movement can create false signals.
• False positives/negatives: algorithm detection may misclassify rhythms, and patient-triggered systems may miss asymptomatic events.
• Limited leads: morphology interpretation is constrained compared with a standard 12‑lead ECG.
• Sampling bias: recordings reflect what was captured, not everything that occurred; absence of captured arrhythmia is not the same as absence of arrhythmia.
• Timing and clock drift: if device time is incorrect, symptom correlation and clinical decisions may be affected.

Best practice is to integrate Event monitor findings with history, exam, and other tests, and to document uncertainty when present.

What if something goes wrong?

When Event monitor workflows fail, the most common operational outcome is lost diagnostic value (uninterpretable data, missing transmissions, incomplete monitoring). The most important safety outcome is delayed recognition of a patient who needs urgent evaluation. Your response should prioritize patient safety, device integrity, and documentation.

Troubleshooting checklist (practical and non-brand-specific)

• Confirm the device is powered on and has adequate battery/charge.
• Check electrode adhesion and placement; replace electrodes if lifting or dry.
• Re-prep the skin (as permitted) and ensure it is clean and dry.
• Inspect lead wires and connectors for looseness or damage.
• Reduce cable motion: secure leads with tape or clips if allowed by policy.
• Ask the patient to remain still briefly to assess baseline noise vs motion artifact.
• Confirm the device clock/time is correct if time correlation matters in your workflow.
• Verify transmission steps (hub powered, phone app permissions, connectivity available).
• Confirm the patient knows how to trigger and confirm an event capture (if patient-activated).
• Review whether the issue is environmental (high EMI area) and relocate if feasible.

When to stop use

Stop use and escalate according to facility policy if:

• The device shows signs of damage, overheating, fluid ingress, or electrical hazard.
• Skin injury is developing (blistering, open wounds) at electrode sites.
• The device repeatedly produces unreadable tracings despite correct setup.
• There is a concern that the device is assigned to the wrong patient or data integrity is compromised.

For worsening symptoms or concern for an acute condition, follow the facility’s clinical escalation pathways rather than relying on the device.

When to escalate to biomedical engineering or the manufacturer

Escalate to biomedical engineering for:

• Physical damage, failed self-test, battery issues, broken leads, or repeated functional failures.
• Questions about cleaning compatibility, disinfection products, or safe reprocessing.
• Asset tracking, preventive maintenance, and electrical safety concerns.

Escalate to the manufacturer/vendor support (per contract) for:

• Software platform failures, transmission outages, or account/access problems.
• Recurring device error codes not resolved by basic troubleshooting.
• Requests for IFU clarification or accessory compatibility confirmation.

Documentation and safety reporting expectations

General good practice includes:

• Document the problem, troubleshooting steps, and whether monitoring time was lost.
• Document patient education and any replacement device issued (with serial number linkage).
• Use local incident reporting systems for device malfunctions or near-miss events.
• Preserve device logs/data when needed for investigation, following privacy policies.

Infection control and cleaning of Event monitor

Infection prevention for Event monitor focuses on preventing cross-contamination between patients and protecting staff during handling of returned devices. Most Event monitor components contact intact skin, but they are frequently touched, transported, and handled in mixed environments (home, clinic, transport bags), which increases contamination risk.

Cleaning principles

• Follow the manufacturer’s IFU (Instructions for Use) and the facility infection prevention policy; if they conflict, escalate for resolution rather than improvising.
• Treat reusable recorders and cables as high-touch items.
• Remove and discard single-use components (electrodes, adhesive patches) according to local waste policy.
• Avoid practices that can damage the device (soaking, spraying into ports, or using unapproved chemicals).

Disinfection vs. sterilization (general concepts)

• Cleaning removes visible soil and reduces bioburden; it is usually required before disinfection.
• Disinfection uses approved agents to reduce microorganisms on surfaces; this is commonly appropriate for noncritical devices that contact intact skin.
• Sterilization is generally reserved for items entering sterile body sites; most external Event monitor recorders are not designed for sterilization methods such as autoclaving. Varies by manufacturer.

High-touch points to prioritize

• Buttons and event markers.
• Screen areas (if present).
• Cable junctions and connectors.
• Belt clips, straps, and carrying cases.
• Charging docks and reusable hubs.

Example cleaning workflow (non-brand-specific)

1. Don appropriate PPE per policy (at minimum, gloves).
2. Remove and discard disposable electrodes/adhesives.
3. Inspect for damage and soil; if heavily soiled, follow the facility’s pre-clean steps.
4. Wipe all external surfaces with an approved disinfectant wipe, respecting contact time.
5. Prevent fluid ingress: do not saturate openings, ports, or seams.
6. Allow to air dry completely.
7. Function-check the device (power on, basic response) if required by local process.
8. Tag and segregate devices that fail inspection; do not return them to circulation.
9. Store clean devices in a designated clean area with clear “ready for use” labeling.

Medical Device Companies & OEMs

In procurement and service planning, it is important to separate the brand on the box from the broader supply chain that makes the product reliable over years of clinical use.

Manufacturer vs. OEM (Original Equipment Manufacturer)

• A manufacturer is the company that markets the final medical device and is typically responsible for regulatory compliance, labeling, post-market surveillance, and overall quality management.
• An OEM (Original Equipment Manufacturer) may produce key components (sensors, batteries, plastics, cables) or even complete subassemblies that are incorporated into the final product.
• OEM relationships matter because they can affect component availability, long-term serviceability, and consistency of accessories (for example, electrodes and lead sets). The extent of OEM involvement varies by manufacturer and is not always publicly stated.

For Event monitor programs, OEM and supply-chain considerations often show up as: accessory compatibility, lead durability, battery performance, software platform support, and replacement part availability.

Rural access and continuity of follow-up can be limiting factors, making program design as important as device selection.

Key Takeaways and Practical Checklist for Event monitor

• Define the clinical question before selecting an Event monitor workflow.
• Match monitoring duration to symptom frequency using local protocols.
• Confirm whether the device is patient-activated, auto-triggered, or both.
• Teach patients how to trigger and confirm event capture, if applicable.
• Validate ECG signal quality before the patient leaves the clinic.
• Use correct electrode placement to reduce artifact and false events.
• Standardize skin prep steps to improve adhesion and trace quality.
• Document device serial number/asset tag against the correct patient record.
• Record start time, planned stop time, and return logistics clearly.
• Provide simple, language-appropriate written instructions with pictures.
• Plan for patients without smartphones or reliable connectivity.
• Establish who reviews transmissions and how quickly review occurs.
• Define escalation rules for “urgent” transmissions within your service.
• Treat algorithm rhythm labels as suggestions, not definitive diagnoses.
• Always correlate Event monitor tracings with symptoms and context.
• Expect artifact from motion, loose electrodes, and muscle activity.
• Replace electrodes promptly when adhesion fails or noise increases.
• Stop use for damaged housings, frayed cables, or fluid ingress.
• Use only manufacturer-approved chargers, batteries, and accessories.
• Follow biomedical engineering commissioning and electrical safety policies.
• Include preventive maintenance and function checks in asset management.
• Budget for consumables; electrodes and patches drive ongoing costs.
• Separate clean storage from returned-device holding areas.
• Clean and disinfect reusable parts strictly per IFU and IP policy.
• Never soak recorders or spray fluids into ports or seams.
• Discard single-use electrodes/patches; do not attempt reprocessing.
• Inspect and tag devices that fail cleaning inspection or function checks.
• Train staff on troubleshooting: battery, electrode contact, connectivity.
• Build a clear pathway for vendor support and warranty returns.
• Audit lost-to-follow-up rates and strengthen retrieval workflows.
• Protect patient-identifiable data with role-based access and audit trails.
• Review cybersecurity requirements for connected Event monitor platforms.
• Ensure time synchronization if your workflow depends on timestamps.
• Create a standard report template for consistent clinical documentation.
• Track turnaround time from monitoring end to clinician over-read.
• Close the loop: communicate results to patients per policy.
• Encourage reporting of device malfunctions and near-miss misassignments.
• Keep spare leads, chargers, and electrodes to prevent service interruption.
• Evaluate distributors on training quality, spares availability, and response time.
• Consider total cost of ownership: device, software, service, and consumables.
• Align procurement decisions with cardiology capacity and reading workflows.
• Reassess the program regularly using quality and safety indicators.
