ABSTRACT:
A method and apparatus for attenuating polarization voltages or "afterpotentials" which develop at the heart tissue/electrode interface following the delivery of a pacing stimulus to the heart tissue such that the evoked response of the heart may be accurately detected to determine whether each pacing stimulus resulted in heart capture or contraction, thereby facilitating improved tracking of the capture threshold for minimizing power consumption while assuring therapeutic efficacy. The conventional large capacitance coupling capacitor used to suppress DC components of the pacing pulse is reduced to effectively lower the equivalent capacitance of the pacing and coupling capacitors following delivery of the pacing pulse, allowing shorter recharge and blanking intervals. As a result, the evoked response is more easily detected.
