Abstract:
1. An implantable medical device, comprising: an input circuit sensing cardiac signals; a microprocessor detecting a predetermined event in response to the sensed signals; a first circuit delivering a first therapy; a second circuit for delivering a second therapy, the second circuit including an energy storage device to store energy associated with the second therapy and a charging circuit selectively coupled to the storage device to transfer a predetermined level of the stored energy to the charging circuit; and a control circuit controlling the first circuit and the second circuit to deliver the first therapy substantially simultaneous with coupling of the charging circuit and the energy storage device in response to the predetermined event being detected, and decoupling the energy storage device and the charging circuit during a redetect period subsequent to delivery of the first therapy and prior to the predetermined level of the stored enemy being transferred to the charging circuit, wherein the control circuit recouples the energy storage device and the charging circuit in response to the microprocessor detecting the predetermined event during the redetect period.
