Monitoring short term fluctuations in PR intervals following premature ventricular contractions
First Claim
1. For use with an implantable system, a method of performing at least one of a cardiac assessment and an autonomic assessment, comprising:
- (a) monitoring short-term fluctuations in PR intervals that follow a premature ventricular contraction; and
(b) performing, using a processor of the implantable system, at least one of a cardiac assessment and an autonomic assessment, based on the monitored fluctuations in PR intervals that follow the premature ventricular contraction.

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.
