1. In an implantable system, a method of detecting myocardial ischemic events, comprising:

  • (a) monitoring short-term fluctuations in cardiac intervals that follow premature ventricular contractions;

    (b) detecting myocardial ischemic events based on the monitored fluctuations; and

    (c) performing one or more of the following in response to detecting myocardial ischemic events at step (b);

    triggering myocardial ischemia therapy, transmitting an alert that an action appropriate to detection of myocardial ischemia should be taken, or storing a measure of myocardial ischemia burden.
