Abstract
Methods and apparatus for classifying cardiac rhythm by analyzing sensed atrial and ventricular heartbeats, and determining if the rhythm might be pace-terminable in a given chamber. The method maintains a histogram of the sensed beat interval in the chamber of interest and a second histogram of conduction time from the other chamber. The method classifies a rhythm as pace terminable in the given chamber when the intervals in that chamber are stable, and the conduction times to that chamber are unstable. It applies further criteria when the intervals in the given chamber are stable, and the conduction times are also stable. Antitachycardia pacing is deliverable to terminate tachyarrhythmias determined to be pace terminable.
