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 1):
A medical device comprising operational circuitry and a plurality of electrodes electrically coupled to the operational circuitry, the operational circuitry being configured to perform a method of cardiac signal analysis comprising:\n the operational circuitry receiving an electrical signal from the electrodes and detecting a series of events in the electrical signal and identifying intervals between consecutive detected events; the operational circuitry using morphology analysis to identify overdetections of electrical signals emanating from the heart of a patient in the series of events; whenever an overdetection is identified, the operational circuitry combining an interval preceding the overdetection and an interval following the overdetection to form a combined interval; following the morphology analysis to identify overdetections, the operational circuitry certifying combined intervals and intervals that are not adjacent to overdetections; and the operational circuitry estimating a cardiac rate using only the certified intervals.
