First Claim
Patent Images
1. A method, comprising:
- sensing a cardiac signal;
initiating an arrhythmia episode detection process in response to the cardiac signal by enabling an arrhythmia detection counter to be adjusted during the detection process;
accumulating data relating to cardiac events during the detection process;
establishing an arrhythmia episode profile using the accumulated data; and
discriminating between arrhythmia episode types in response to the established profile, wherein accumulating data comprises determining a pattern of the adjustment of the counter during the detection process.

Abstract
A medical device and associated method sense a cardiac signal and initiate an arrhythmia episode detection process in response to the cardiac signal by enabling an arrhythmia detection counter to be adjusted during the detection process. Data is accumulated relating to cardiac events during the detection process. An arrhythmia episode profile is established using the accumulated data. The accumulated data includes a pattern of the adjustment of the detection counter during the detection process
