Abstract
An implantable pacemaker is provided with subcutaneous spiral electrodes for sensing electrical signals of the heart. Subcutaneous spirals or spiral electrodes are embedded individually into three or four recessed casings placed in a compliant surround that is attached to the perimeter of the implanted medical device. The electrodes are electrically connected to the circuitry of the implanted pacemaker and detect cardiac depolarization waveforms displayable as electrocardiographic tracings on an external instrument such as a programmer. The spiral electrode constitutes the proximal end of a continuous wire that upon egress from the recessed casing is insulated using insulative material.
