Patent Images
1. A method of cardiac pacing, comprising:
- pacing a patient'"'"'s heart in a tachyarrhythmia prevention pacing mode for a first extended time period extending over more than one day;
defining a desired range for a metric of success of said tachyarrhythmia prevention pacing mode;
monitoring said metric over said first extended time period;
in response to said monitored metric falling outside said range, adjusting parameters of said tachyarrhythmia prevention pacing mode to vary aggressiveness of said tachyarrhythmia prevention pacing mode.

Abstract
A cardiac pacemaker and a method of its use. The pacemaker paces a patient'"'"'s heart in a tachyarrhythmia prevention pacing mode for an extended time period, defines a metric of success of the tachyarrhythmia prevention pacing mode, monitors the metric over the extended time period and, responsive to the monitored metric, adjusts the tachyarrhythmia prevention pacing mode. Adjustment of the tachyarrhythmia prevention pacing mode may take the form of pacing the patient'"'"'s heart with a different set of electrodes, pacing the patient'"'"'s heart with a different tachyarrhythmia prevention pacing mode and/or terminating operation of the tachyarrhythmia prevention pacing mode.
