Abstract:
1. A method of improved ectopic beat detection by an implantable cardiac rhythm management device comprising the steps of: (a) providing a cardiac rhythm management device having an atrial event detector, a ventricular event detector and a microprocessor-based controller coupled to the atrial event detector and the ventricular event detector and programmed to determine PR intervals, RR intervals and AA intervals from detected atrial and ventricular events; (b) determining an average time interval between an atrial event and next occurring ventricular event over a predetermined number of heartbeat cycles (PR (c) indicating an ectopic beat when a PR interval of a given heartbeat cycle is less than about 80 percent of PR (d) determining whether said given heartbeat cycle is possibly ectopic when the PR interval of said given heartbeat cycle is less than about 80 percent of PR
