DETECTING ARRHYTHMIAS IN A SUBCUTANEOUS MEDICAL DEVICE

摘要

A method and apparatus for detecting a cardiac event in a medical device that includes sensing cardiac signals from a plurality of electrodes forming a first sensing vector and a second sensing vector, advancing from a first state to a second state in response to processing of an interval associated with a cardiac cycle of the sensed cardiac signals, and advancing from the second state in response to processing of a cardiac signal sensed during a predetermined sensing window.
