IMPLANTABLE MEDICAL DEVICE WITH MEANS FOR DETERMINING IF SHOCKABLE RHYTHM CLASSIFICATION CRITERIA ARE MET, INCLUDING DETERMINING T-WAVE OVERSENSING

摘要

A medical device coupled to extracardiac electrodes is configured to analyze a cardiac electrical signal over a signal analysis segment to determine if shockable rhythm classification criteria are met (104), determine that TWOS detection criteria are met for the signal analysis segment when a predetermined number of TWOS analysis windows are classified as TWOS and classify the signal analysis segment as non-shockable in response to determining that the TWOS detection criteria are met.
