A medical device is configured to determine time intervals between successive cardiac events sensed from a cardiac electrical signal, to increase a value of a tachyarrhythmia interval count in response to each determined time interval that is detected as a tachyarrhythmia interval. The device is further configured to detect normal sinus rhythm events and to decrease the value of the tachyarrhythmia interval count in response to detecting a threshold number of normal sinus rhythm events.
