The HeartStart MRx has an easy-to-use interface that helps you respond quickly. Communication and collaboration with your hospital care teams is simple. And when it’s time to hand-off from a HeartStart FR3, you don’t need to change pads.
Rich clinical information, driving patient care
With the DXL 12-Lead ECG algorithm, the HeartStart MRx gives advanced STEMI decision support. There are predictive tools that show the probability that the patient is experiencing acute ischemia or the likely outcome of AMI. These tools help you make confident decisions to speed triage.
Built to endure, designed to evolve
The HeartStart MRx is built tough—tough enough to endure environmental conditions created by water, vibrations, mechanical shocks, drops, and electromagnetic activity. Plus it’s built on a scalable platform, so you can upgrade easily and take advantage of Philips advancements while retaining the same footprint and weight.
