Abstract:
1. An implantable cardiac rhythm management device, comprising: a sensing channel for sensing an electrogram signal representing cardiac electrical activity and circuitry for generating a chamber sense when the electrogram signal exceeds a specified threshold; one or more stimulation channels for delivering electrical stimulation to a subject's heart; an activity sensor for measuring an activity level; a controller programmed to detect a tachyarrhythmia from the rate at which chamber senses are generated and to cause delivery of anti-tachyarrhythmia therapy through one or more of the stimulation channels upon detection of a tachyarrhythmia; a telemetry interface by which the controller may communicate with an external device; wherein the controller is programmed to disable the delivery of anti-tachyarrhythmia therapy for a specified time interval upon receipt of a temporary suspend command from the external device via the telemetry interface and to re-enable the delivery of anti-tachyarrhythmia therapy upon expiration of the specified time interval; and, wherein the controller is programmed to re-enable delivery of anti-tachyarrhythmia therapy before expiration of the specified time interval upon measurement of an activity level above a specified threshold value.
