Abstract
An implanted receiver-decoder stores program bits corresponding to rate alteration and to input amplifier sensitivity. The former bits operate a rate decoder which in turn is responsive to predetermined outputs of a fixed rate oscillator-counter. The input amplifier is connected to the intermediate tap of a potential divider, one arm of which senses signals at the heart, and the other of which is either set at a fixed potential, or is allowed to float, under control of the input amplifier sensitivity programming signal.
