Abstract
A cardiac amplifier system with several patient electrodes includes an amplifier with a capacitor coupled input and a switch for coupling different ones of the patient electrodes to the amplifier. A circuit including a time delay, a pair of sequentially operated controlled conduction devices and a resistive network shunts the amplifier input and charges the coupling capacitors in a controlled fashion when the selector switch is operated to prevent switching transients from being applied to the amplifier.
