Abstract
A medical device and associated method for discriminating cardiac events includes determining whether a first match score is within a first match zone having a first correlation with a non-treatable cardiac event, a second match zone having a second correlation with the non-treatable cardiac event less than the first correlation, a third match zone having a first correlation with a treatable cardiac event, and a fourth match zone having a second correlation with the treatable cardiac event greater than the first correlation with the treatable cardiac event. In response to the first match score being within one of the first and second match zones, a determination is made whether consecutive match scores are within the first match zone and whether a break in the treatable cardiac event has occurred. Cardiac evidence is accumulated in response to determining whether a break has occurred and utilized to discriminate cardiac events.
