Microsim 400 - ARH Patient Simulator
5 Lead ECG & Arrhythmia

The MicroSim 400 - ARH is a microprocessor based, pocket-sized patient simulator designed for testing the performance of ECG equipment. A normal sinus rhythm waveform with five selectable rates and 10 arrhythmia waveforms are available. The portability of the MicroSim        400 - ARH makes it ideal for the busy technician to quickly verify the operation of arrhythmia and telemetry systems.
