Abstract
An apparatus for producing signals indicative of power levels of depolarizations of heart tissue, particularly adapted for use in an implantable antiarrhythmia device or an implantable pacemaker. The device distinguishes between the power level of sensed depolarization signals in order to distinguish between different types of depolarization waveforms. In particular, the measured power level of the sensed depolarizations may be employed to distinguish between normally conducted and ectopic beats, for use in controlling the operation of an implantable antiarrhythmia device such as an implantable pacemaker/cardioverter/defibrillator or for use in controlling the operation of a bradycardia pacemaker.
