Abstract
Implantable systems, and methods for use therein, perform at least one of a cardiac assessment and an autonomic assessment. Short-term fluctuations in PR intervals, that follow the premature contractions in the ventricles, are monitored. At least one of a cardiac assessment and an autonomic assessment is performed based on the monitored fluctuations in PR intervals that follow the premature contractions in the ventricles. This can include assessing a patient's risk of sudden cardiac death (SCD), assessing a patient's autonomic tone and/or detecting myocardial ischemic events based on the monitored fluctuations in PR intervals that follow the premature contractions in the ventricles.
Claims10
For use with an implantable system, a method of performing at least one of a cardiac assessment and an autonomic assessment, comprising:
- (a) monitoring morphology of a signal that is indicative of PR intervals that follow premature contractions of the ventricles;
- and
- (b) performing at least one of a cardiac assessment and an autonomic assessment, based on the monitored morphology of the signal that is indicative of PR intervals that follow premature contractions of the ventricles.
An implantable system for performing at least one of a cardiac assessment and an autonomic assessment, comprising:
- means for monitoring morphology of a signal that is indicative of PR intervals that follow premature contractions of the ventricles;
- and
- means for performing at least one of a cardiac assessment and an autonomic assessment, based on the monitored morphology of the signal that is indicative of PR intervals that follow premature contractions of the ventricles.
