Abstract

An implantable medical device (IMD) (101, 501) is described herein. The IMD (101, 501) includes sense circuitry (116, 544, 550) configured to produce a differential signal indicative of a voltage potential difference between first and second electrodes (112, 114). The IMD (101, 501) additionally includes disturbance detection circuitry (210) configured to detect a non-biological disturbance based at least in part on a slew rate of the differential signal exceeding a slew rate threshold. The IMD (101, 501) includes a controller (120, 520) communicatively coupled to the sense circuitry (116, 544, 550) and the disturbance detection circuitry (210) and configured to detect based on the differential signal an episode of asystole, an episode sinus pause, a premature ventricular contraction, or premature atrial contraction, and classify, as a false positive, a detection of the episode of asystole, the episode sinus pause, the premature ventricular contraction, or the premature atrial contraction, when the non-biological disturbance detected by the disturbance detection circuitry (210) at least partially coincides with the detection of the episode of asystole, the episode sinus pause, the premature ventricular contraction, or the premature atrial contraction.
