Abstract:
1. A method of treating a cardiac event of a heart of a patient by a medical device comprising therapeutic componentry and a plurality electrodes, comprising the steps of: sensing cardiac signals from the plurality of electrodes, the plurality of electrodes forming a first sensing vector and a second sensing vector; determining with the medical device whether each one of the first sensing vector and the second sensing vector is corrupted by noise; if the first sensing vector is corrupted by noise and the second sensing vector is not corrupted by noise, determining with the medical device if a cardiac signal sensed by the second sensing vector is indicative of one of a first cardiac rhythm and a second cardiac rhythm different from the first cardiac rhythm; then if the cardiac signal sensed by the second sensing vector is indicative of the first cardiac rhythm, the medical device delivering a first therapeutic output to the patient based, at least in part, on the cardiac signal sensed by the second sensing vector and a cardiac signal sensed by the first sensing vector both being indicative of a first cardiac event; if the cardiac signal sensed by the second sensing vector is indicative of the second cardiac rhythm, the medical device delivering a second therapeutic output to the patient based, at least in part, on the cardiac signal sensed by second sensing vector being indicative of a second cardiac event different from the first cardiac event.
