What is it indicated for?
The NUVANT Mobile Cardiac Telemetry (MCT) System is intended to
continuously measure, record and periodically transmit physiological data.
The System is indicated for those patients who require monitoring for the
detection of non-lethal cardiac arrhythmias such as, but not limited to,
supraventricular tachycardias (e.g. atrial fibrillation, atrial flutter,
paroxysmal SVTs), ventricular ectopy, bradyarrhythmias and conduction
disorders. The NUVANT System monitors, derives and displays:
ECG
Heart Rate
