Title:
DISCRIMINATION OF VENTRICULAR TACHYARRHYTHMIAS IN AN IMPLANTABLE MEDICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/107865
Kind Code:
A1
Abstract:
A method and medical device for discriminating an arrhythmia that includes an input circuit (110) sensing cardiac signals and a microprocessor (100) identifying an event associated with the sensed cardiac signals as a first arrhythmia event. A first circuit (107) delivers a first therapy, substantially simultaneous with coupling of a charging circuit (111) and an energy storage device (109) to generate stored energy on the energy storage device, in response to the first arrhythmia event, and a control circuit (106) controls delivery of the first therapy by the first circuit. The microprocessor evaluates a physiologic response to the delivered first therapy and determines the event is other than the first arrhythmia event in response to the evaluated physiologic response.
