Abstract
Abstract An apparatus which provides an electromagnetic field in synchronization with the occurrence of a detected heart function potential is located outside of a patient''s body in which a heart stimulator having a constant rhythm frequency generator has been implanted. The implanted generator is magnetically coupled within the electromagnetic field so as to be responsive to the occurrence thereof. An electrical heart stimulus in synchronization with the detected potential is thereby enforced from the implanted generator in response to the occurrence of the field. Coupled stimulation is provided by the apparatus by routing the detected signal along an additional branch path which includes a delay line. The delayed signal provides a second electromagnetic field a preselected delayed time after the provision of the synchronized field whereby a synchronized heart stimulus and a second, coupled heart stimulus are provided in response to a single detected heart function potential.
