Abstract
Cardiac stimulating apparatus comprising a first external unit for transmitting electromagnetic energy within the patient's body to be received by a second, surgically implanted unit within the patient's body and adapted to be solely powered by the transmitted electromagnetic energy. The first external unit transmits a power signal and a control signal, the power signal comprising a first pulse for energizing the second internal unit, and the control signal for controlling the internal unit to pace the patient's heart in a variety of modes, e.g., atrial, ventricular and atrial/ventricular sequential pacing.
