Abstract:
1. A machine-assisted method comprising: sensing an intrinsic electrical heart signal using an implantable medical device; detecting a first tachyarrhythmia episode using the intrinsic electrical heart signal; selecting a first tachyarrhythmia template from a group of two or more candidate supraventricular tachyarrhythmia (SVT) templates; comparing at least a portion of the intrinsic electrical heart signal obtained during the first tachyarrhythmia episode to the selected first tachyarrhythmia template, the first tachyarrhythmia template representative of a signal morphology of a first type of tachyarrhythmia; and declaring whether the detected first tachyarrhythmia episode constitutes the first type of tachyarrhythmia based on the comparison.
