Abstract:
Methods, systems, and devices for signal analysis in an implanted cardiac monitoring and treatment device such as an implantable cardioverter defibrillator. In illustrative examples, captured data including detected events is analyzed to identify likely overdetection of cardiac events. In some illustrative examples, when overdetection is identified, data may be modified to correct for overdetection, to reduce the impact of overdetection, or to ignore overdetected data. New methods for organizing the use of morphology and rate analysis in an overall architecture for rhythm classification and cardiac signal analysis are also discussed.

Claim (Index 10):
The device of  claim 1  wherein the operational circuitry is further configured such that each detected event is affiliated with a sample window composed of a number of signal amplitude samples and the morphology analysis includes Wide Complex Analysis in which an overdetection is identified when first and second detected events are separated by an interval that is shorter than a predetermined Wide Complex threshold interval and at least one of the following conditions is identified:\n the first and second detected events are of opposing polarity; or \n a Peak interval for the first and second detected events is less than a predetermined threshold, \n wherein the Peak interval is defined as the lesser of:\n a) an interval between the maximum amplitude sample of the first detected event and the maximum amplitude sample of the second detected event, and \n b) an interval between the minimum amplitude sample of the first detected event and the minimum amplitude sample of the second detected event; \n such that, if the Wide Complex analysis is satisfied, one of the first and second events is marked as an overdetection.
