Trackmaster TMX-428 Treadmill for Stress Testing

Overview

The Trackmaster TMX-428 treadmill is a professional-grade stress test treadmill engineered specifically for cardiac exercise testing in hospitals, cardiology clinics, and diagnostic centers.
Built around the industry’s widest 22-inch running belt and a low-profile cushioned deck, the TMX-428 delivers the patient safety, operational accuracy, and long-term reliability that clinical environments demand.

Unlike general-purpose treadmills, the TMX-428 is designed exclusively for OEM stress testing systems and authorized medical distributors, making it a purpose-built clinical tool — not a repurposed fitness machine.
At AIM Cardio, we offer the TMX-428 refurbished to like-new condition with warranty and unlimited technical support included.

Built for Clinical Stress Testing

The Trackmaster TMX-428 was designed from the ground up for one purpose: accurate, repeatable stress testing in clinical environments.
Its smooth and quiet drive system, wide running surface, and precise speed control help ensure consistent test conditions across patients and protocols, which is essential for reliable cardiovascular data.

The TMX-428 is compatible with leading cardiac stress testing systems and has been widely deployed in cardiology labs, hospital stress centers, and outpatient diagnostic facilities.
Its self-calibrating speed and elevation eliminate the need for frequent manual adjustments, reducing both technician workload and potential for human error during testing.

Safety and Patient Comfort

The TMX-428 was engineered with patient safety as a primary design priority.
The wide 22-inch belt, low 7-inch step-up height, cushioned shock-absorbing deck, and full wrap-around handrails work together to give patients more stability and confidence throughout the test.

The emergency stop button is prominently positioned for fast access by the technician, and the patient safety tether automatically halts the belt if the patient moves too far from the front panel.
When activated, the tether locks the belt for approximately 45 seconds, giving the clinical team time to respond safely.
These features make the TMX-428 a strong choice for facilities that test elderly patients, post-cardiac patients, or anyone with limited mobility.

Compatible Stress Testing Systems

The Trackmaster TMX-428 is designed to integrate with leading stress testing platforms used in cardiology and diagnostic settings.
It is commonly paired with systems from Welch Allyn, Schiller, Midmark, Norav, and other OEM stress ECG platforms through its RS-232 serial and USB 1.0 communication ports.

This broad compatibility makes the TMX-428 a flexible choice for facilities upgrading their treadmill while keeping their existing stress testing software and ECG hardware.
If you need to verify compatibility with a specific system, our technical team can assist before purchase.

Typical Applications

• Cardiac stress testing and exercise ECG assessment in hospital and outpatient settings.
