ABSTRACT:
An implantable medical device includes electrodes coupled to a patient's heart and sensing circuitry having inputs connected to the electrodes for sensing analog cardiac electrical signals from one of the atrial or ventricular channels. The sensing circuitry includes waveform digitization network means for converting the analog atrial or ventricular electrical signals into a parallel output format sign/magnitude digitized output signal.
