What Is the GE 700044-203 Compatible AM4 Patient Interface Cable?

The GE Healthcare 700044-203 compatible EKG patient interface cable is a reusable, aftermarket cable that connects the AM4 acquisition module to a GE Marquette electrocardiograph or stress testing system. The patient’s leadwires plug into the AM4, which sits near the patient and acquires the 12-lead ECG. This cable carries that signal back to the host system for display, analysis, and printing. Because it is the only link between the module and the host, a failing cable can stop ECG acquisition entirely. It is a compatible replacement, not an original GE part, and it is built to the same fit, form, and function as the OEM 700044-203 cable.

Compatible Equipment Models

This compatible cable is confirmed for use with the GE Marquette AM4 and AM5 acquisition modules on the MAC 6, MAC 12, MAC 15, and MAC PC electrocardiographs, the CASE 12 and CASE 15 exercise stress systems, and the CENTRA system. These platforms remain in service at many clinics and stress labs. This cable is not for the CAM 14 module used on the MAC 5000 and MAC 5500, which needs a different interface cable, so confirm which acquisition module your systems use before ordering.

Design and Construction

The cable is 4.3 ft (1.3 m) long, a compact length suited to setups where the module stays close to the cart or stress system. One end has a rectangular connector that matches the AM4 interface, and the other end has a registered-jack (RJ-style) modular connector. The gray TPU jacket stays flexible, resists kinks, and holds up to routine cleaning between patients. The cable is latex-free, non-sterile, weighs about 0.7 lbs, and ships one per bag.

When to Replace Your AM4 Patient Interface Cable

Interface cables flex constantly at both connectors, and older AM4-era systems often have cables that have been in service for many years. Replace the cable when the system reports no acquisition module or a module communication error, when the ECG trace freezes or drops out as the cable is moved, when all leads show noise at once (a sign the fault is upstream of the leadwires), or when you find a cracked jacket, a broken latch on the RJ-style connector, or damaged pins on the rectangular connector. Swapping in a known-good cable is the fastest way to confirm the diagnosis before sending the AM4 module out for repair.

Cross Reference and Interchange Part Numbers

This compatible AM4 patient interface cable, IPR Medical SKU EKT-GE-AM4-S, cross-references to GE Healthcare Marquette part number 700044-203 and to Unimed part number EAM-GE4-S. Materials managers and purchasing staff can use either number to confirm the match against existing inventory, work orders, or requisitions. For MAC 5000 and MAC 5500 systems with the CAM 14 module, IPR Medical also stocks the compatible GE 2016560-001 and 2016560-003 interface cables.
