Description
The Welch Allyn ELI 230 Resting Electrocardiograph with Wireless Patient Cable Module (WAM), UK plug, is a compact and portable 12-lead ECG system designed for adult and paediatric resting ECGs. It combines full diagnostic functionality with a high-resolution colour display, integrated thermal printer and the VERITAS resting ECG interpretation algorithm. The device offers real-time preview of 3, 8 or 12 leads and post-acquisition review of acquired ECGs, while the ‘Best 10’ feature automatically selects the highest-quality 10-second segment from up to 1 minute of internally buffered data to reduce repeat tests. Supplied with the WAM wireless acquisition module, it allows cable-free data acquisition at the patient bedside, increasing workspace flexibility and enabling the electrocardiograph to remain away from the immediate patient area. This UK configuration includes a UK mains plug and is intended for use in hospitals, clinics and primary care settings.

Packaging
ELI 230 portable 12-lead resting electrocardiograph base unit with VERITAS interpretation (configuration dependent)
WAM wireless patient cable module with 12-lead ECG patient cable and replaceable lead wires
Hospital-grade mains power cord with UK plug
Starter pack of ECG thermal paper roll(s) suitable for the integrated printer (exact quantity may vary by region)
Tab electrodes and/or clip adapters and banana clips starter accessories (depending on distributor’s standard kit configuration)
Packaging box with protective inserts to secure the device and accessories during transport
Usage
Only trained and qualified healthcare professionals should operate the ELI 230; always follow the official Welch Allyn/Baxter user manual and local clinical protocols.
Place the ELI 230 base unit on a stable, flat surface near the patient area and connect the power cord to a suitable mains socket with the UK plug, or ensure the internal battery is adequately charged.
Prepare the patient according to standard 12-lead ECG procedures: position the patient comfortably, expose required areas, clean and lightly abrade skin if necessary, and apply electrodes in the correct anatomical positions.
Attach the electrodes to the WAM patient cable using appropriate tabs/clips, ensuring each lead is connected to the correct anatomical location and that cables are not under tension or causing patient discomfort.
Power on the WAM wireless acquisition module and confirm that it is correctly paired with the ELI 230 base unit; verify that lead status and signal quality indicators on the display are acceptable.
Use the colour display to preview ECG waveforms; correct any lead-off or artefact issues by adjusting electrodes or patient position as needed.
Acquire a resting ECG by pressing the designated acquisition button on the WAM or the base unit; the device will capture ECG data, apply the Best 10 selection (if enabled) and store the best 10 seconds of ECG from the one-minute buffer.
Review the acquired ECG on the display and print a full-size ECG report using the integrated thermal printer; if interpretation is enabled, review VERITAS diagnostic statements as a support tool, not a substitute for clinical judgement.
If configured for connectivity, follow local procedures for exporting or integrating ECG data into ECG management systems, EMR or other archives.
After the examination, remove and dispose of single-use electrodes, clean and disinfect the patient cable, WAM module and device surfaces using only manufacturer-approved cleaning agents and methods.
Regularly check paper levels, battery charge status and cable integrity; schedule preventive maintenance and calibration as recommended by the manufacturer or local biomedical engineering services.
Contraindications
The ELI 230 itself has no specific clinical contraindications for recording a standard resting ECG; its use should be based on the judgement of a qualified healthcare professional.
Do not use the device in the presence of flammable anaesthetic gas mixtures with air, oxygen or nitrous oxide due to explosion risk associated with electrical equipment.
Avoid use in environments with strong electromagnetic interference (for example, in close proximity to MRI systems or certain electrosurgical units) that may compromise ECG signal quality.
Do not use unapproved patient cables, electrodes or accessories, or modified components, as these may affect safety, performance and regulatory compliance.
Use caution in patients with implanted devices and follow manufacturer guidance; while the system supports pacemaker detection, ECG interpretation must still be performed carefully by a clinician.
Adverse Effects
Mild and transient skin irritation, erythema or discomfort at electrode sites due to adhesive or skin preparation agents.
Rare allergic responses to electrode adhesives or gels; these are attributable to consumables rather than the ECG device.
Minor discomfort from remaining still during ECG acquisition, particularly in frail or acutely unwell patients.
Incorrect electrode placement or poor contact may lead to misleading or artefact-laden ECGs; while not an adverse physiological effect, this can affect diagnostic quality and requires repeat recording.
Storage Conditions
Store the ELI 230 and WAM module in a clean, dry environment, protected from dust, excessive moisture and direct sunlight.
Keep the device within the temperature and humidity ranges specified in the official technical/user documentation; avoid extreme heat, cold or rapid temperature changes.
When not in use, place the device on a stable surface or dedicated cart, ensure it is powered down or in standby as appropriate, and avoid placing heavy objects on top of it.
Maintain the battery according to manufacturer instructions (for example, periodic charging cycles) to preserve battery capacity and operational readiness.
Protect accessories such as patient cables, WAM module and power cords from kinking, crushing or chemical exposure; store neatly coiled or in designated compartments.
If the device is stored for extended periods, inspect it and perform functional checks before returning it to routine clinical service.
Duration
Per resting ECG, the ELI 230 typically records and analyses a 10-second ECG interval selected from up to 1 minute of buffered data. Overall procedure time, including patient preparation and electrode placement, usually ranges from a few to several minutes, depending on clinical context.
Onset
Immediate in diagnostic terms: ECG waveforms are displayed in real time as soon as acquisition begins and the final 10-second resting ECG and any interpretive statements are available immediately after acquisition and processing.
