Abstract
A pacemaker sense amplifier which includes active circuitry which establishes and maintains a constant field density between two electrode poles, effectively clamping them together at a substantially fixed potential difference. The amount of current or power required to maintain this condition in the steady state is monitored and forms the basis of detection of the passing depolarization wavefront.
