Abstract:
1. A method comprising: receiving a cardiac electrical signal and monitoring heart rate based on the cardiac electrical signal; detecting a tachyarrhythmia based on the monitored heart rate exceeding a first predetermined threshold; determining whether the detected tachyarrhythmia is a non-sustained tachyarrhythmia based on the length of the detected tachyarrhythmia episode; identifying a plurality of events in the cardiac electrical signal during the detected non-sustained tachyarrhythmia episode as cardiac depolarizations; determining a rate of at least some of the identified events; determining that the detected non-sustained tachyarrhythmia is a suspected non-physiological non-sustained tachyarrhythmia caused by a sensing integrity condition, based on the rate of the at least some of the identified events; and storing an electrogram for the suspected non-physiological non-sustained tachyarrhythmia based on the detection, the electrogram including at least a portion of the cardiac electrical signal.
