ABSTRACT:
A heart pacemaker has a controllable time delay element for setting the time between atrial and ventricular activity (AV time). For terminating tachycardia as quickly as possible with such a heart pacemaker, a detector for detecting tachycardia is provided with the time delay element being driven by means of the detector such that the AV time is altered upon the occurrence of tachycardia. The change in the AV time is selected such that the new AV time is an optimum for terminating tachycardia. After a preselected time, the time delay element returns to the original AV time.
