System and method for establishing episode profiles of detected tachycardia episodes
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, wherein determining the pattern of the adjustment comprises storing a notation on each cardiac cycle during the detection process indicating a direction of a counter value change as being one of up, down and no change.

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.
