Abstract
Systems and methods for detecting cardiac arrhythmias such as an atrial fibrillation (AF) are described herein. The AF detection system includes a sensor circuit to sense a physiological signal, a heartbeat processor to recognize a plurality of beat patterns using cycle length of two more consecutive cardiac cycles. The beat patterns can be indicative of temporal relationship between the consecutive cardiac cycles. The heartbeat processor may generate a repetitiveness indictor based on a statistical measurement of various beat patterns. The AF detection system includes an arrhythmia detector to detect an episode of AF based on the repetitiveness indictor, and to discriminate the AF from other arrhythmias of atrio-ventricular conduction abnormalities.
