Abstract
A microprocessor based implantable cardiac treatment device having first and second clocks. The first clock is a continuously running external clock of a relatively low frequency for controlling low power, uncomplicated operations of the device. The second clock runs at a much higher frequency for controlling the complex, high power operations of the microprocessor. Clock control circuitry is provided for activating the second clock only when it is determined that high power calculations are to be made by the microprocessor.
