An apparatus for producing signals indicative of power levels of depolarizat ions of heart tissue, particularly adapted for use in an implantable anti-arrhythmia device or an implantable pacemaker. The device distinguishes between the power level of sensed depolari zation signals in order to distinguish between different types of depolarization wa veforms. In particular, the measure power level of the sensed depolarization may be employed to distinguish between normally conducted and ectopic beats, for use in controlling the operation of an implantable anti-arrhythmia device such as an implantable pacemaker/cardiove rter/defibrillator or for use in controlling the operati on of a bradycardia pacemaker.
