What Is the M1644A Compatible 5-Lead ECG Leadwire?

The IPR Medical EL-PH5-90S-A is a compatible aftermarket (not OEM) 5-lead ECG leadwire that replaces OEM part M1644A. It is a reusable leadwire for limb and chest lead placement, with snap electrode ends, AHA color coding, and a 3.0 ft (0.9 m) length, and it is intended for ECG monitoring. Its lead type is listed in the Specifications table.

Compatible Monitor Models

The EL-PH5-90S-A has a long compatibility list that crosses several monitor manufacturers. Examples include select Spacelabs models such as the 90308, 90425, and PC Bedside, and select Nihon Kohden models such as the BSM-8301A, BSM-8502A, and TEC-7200A. Select Welch Allyn, PaceTech, Biolight, Ivy Biomedical, Physio-Control, Bexen Cardio, Newtech, and Solaris models round out the list, together with the remaining entries in the table. Before you order, check that your monitor is named in the Compatible Monitor Models table on the Specifications tab.

Design and Construction

Five leads cover limb and chest placement, and each one finishes in a snap end that connects to the electrode. The leads follow AHA color coding (RA white, LA black, LL red, RL green, V brown). At 3.0 ft (0.9 m), the shielded leadwire gathers its leads into a molded distal connector. Each reusable leadwire comes packed in its own bag and can be cleaned between patients according to facility protocol.

When to Replace Your 5-Lead ECG Leadwire

Recurring lead-off alarms, a baseline that drifts or turns noisy, and artifact that changes when the leads are moved are usually the first signs that a leadwire is wearing out. Inspect it as well for snaps that no longer grip the electrode, insulation that has cracked or stiffened, and a connector housing that is damaged or has bent pins. Trying a known-good leadwire on the same monitor quickly shows whether the leadwire or the monitor is causing the problem.

Cross Reference and Interchange Part Numbers

Along with OEM part M1644A, this compatible leadwire cross-references to OEM number 989803144991. The full set of interchange numbers, grouped by brand, is in the Cross Reference / Interchange Part Numbers table on the Specifications tab.
