Abstract:
1. A method for operating a cardiac device, comprising: sensing an electrogram signal representing cardiac electrical activity and generating a chamber sense when the electrogram signal exceeds a specified threshold; detecting a tachyarrhythmia from the rate at which chamber senses are generated; delivering anti-tachyarrhythmia therapy through one or more stimulation channels upon detection of a tachyarrhythmia; measuring an activity level; disabling the delivery of anti-tachyarrhythmia therapy for a specified time interval upon receipt of a temporary suspend command from an external device via telemetry and re-enabling the delivery of anti-tachyarrhythmia therapy upon expiration of the specified time interval; and, re-enabling delivery of anti-tachyarrhythmia therapy before expiration of the specified time interval upon measurement of an activity level above a specified threshold value.
