  • Cardiac rhythm management systems and methods using multiple morphology templates for discriminating between rhythms
    Patent number: 7031764
    Abstract: Multiple morphology templates for discliminating between rhythms have been used, such as supraventricular tachyarrhythmias (SVTs) and ventricular tachyarrhythmias (VTs), for delivering a countershock in response to a VT episode, but withholding delivery of such a countershock in response to an SVT episode. In certain examples, the particular morphology used for storing morphological features is selected at least in part using a sensor-indicated activity level of a subject, or a metabolic need of the subject.
