The programming of pulse intervals and the inhibition of the output of an implanted cardiac pacemaker are disclosed. The occurrence of either an output pulse from the implanted unit or of cardiac activity allows for synchronization of the programming unit with the implanted device so the external programmer can control the pulse timing sequence of the implanted unit. The implanted unit can be programmed after each pulse, or as required, to obtain a pulse sequence which may be used to provoke, or terminate, tachyarrhythmias, thus enabling non-invasive electrophysiologic studies, or therapeutic stimulation.
