Abstract (en)
An implanted receiver-decoder stores program bits corresponding to rate alteration and to input amplifier sensitivity. The former bits operate a rate decoder (4) which in turn is responsive to predetermined outputs of a fixed rate oscillatorcounter (1, 2). The input amplifier (12) is connected to the intermediate tap of a potential divider (11, 14, 15), one arm (11) 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.
