Abstract

A heart pacemaker circuit has electrodes connected to the heart of the patient, such as to give arterial and ventricular stimulation to the respective chambers. It incorporates a generator which emits arterial and ventricular simulating pulses alternately to the electrodes on a repetition basis using an asynchronous system. There is a detection and control circuit (40) which picks up the heartbeats in the form of signals. these signals are used to control the oscillators (10, 20) so as to produce an asynchronous pulse in response to the heartbeat frequency. The control circuit measures the rest interval between heartbeats which is uses to establish the asynchronism. There is a feedback signal through an electrif filter (31) to a QRS amplifier (33), to the tacho-cardo detector circuit.
