Abstract
A cardiac pacemaker with a single catheter for insertion into a heart through the vascular system. An electrode system for the catheter including a stimulating electrode at the distal end of the catheter for positioning at the apex of the right ventricle, with the stimulating electrode connected to the pulse generating unit of the pacemaker, and sensing electrodes on the catheter spaced from the stimulating electrode for positioning adjacent to the wall of the right atrium for sensing signals generated by the atrial excitation or P-wave, with the P-wave signals connected as input to the pacemaker for determining the timing of the ventricular stimulating pulses. The sensing electrodes are circumferentially equidistant from the stimulating electrode and provide one or more bipolar signals for the pulse generating unit. In alternative configurations, the stimulating electrode and the sensing electrodes are positioned in various locations within the heart to provide other methods of cardiac control.
