First Claim
Patent Images
1. A method of characterizing a patient'"'"'s supraventricular rhythm while the heart is being paced, comprising:
- pacing the patient'"'"'s heart;
modifying one or more pacing parameters; and
characterizing the patient'"'"'s supraventricular rhythm during a time in which the pacing parameters are modified.

Abstract
A method and system for generating a characterization of one beat of a patient'"'"'s supraventricular rhythm (SVR) involves performing such characterization while the heart is being paced. During SVR characterization, various pacing parameters are modified and the patient'"'"'s supraventricular rhythm is characterized while the pacing parameters are modified. The SVR characterization process is effective in single and multiple chamber pacing modes.

61. A body implantable system for characterizing a patient'"'"'s supraventricular rhythm while the heart is being paced, comprising:
-
a lead system, the lead system comprising electrodes extending into a heart;
a detector system, coupled to the lead system, that detects rate channel signals and shock channel signals sensed by the lead system electrodes;
