Abstract

The stimulation pulse generator (12) of this pacemaker is triggered by a digital computer (10, 11) which determines the pulse interval and the pulse width for the pacemaker pulses transmitted to the heart electrodes via the output terminal (13) by repeatedly running a program. The digital computer comprises a read-only memory (11) with a stored program and a microprocessor (10) which is connected to the stimulation pulse generator (12). The pacemaker can be fully implanted into the body of a patient. <IMAGE>
