ABSTRACT:
An implantable cardiac defibrillator includes electrodes coupled to a patient's heart, sensing circuitry having inputs connected to the electrodes for sensing cardiac electrical signals, charging means for storing a charge, and discharge means for delivering a shock to the heart. The sensing circuitry includes switched capacitor gain/filter means for providing an output signal which is transient-free during a gain change operation and which maintains a constant filter bandwidth for each gain setting.
