WIDE-BAND EVOKED RESPONSE SENSING FOR CAPTURE VERIFICATION |
摘要 |
A cardiac rhythm management device having a capture verification sensing circuit for use in either a normal beat to beat pacing mode or an autothreshold mode. The cardiac rhythm management device is coupled to one or more pacing leads having pacing/sensing electrodes coupled thereto, and includes a sensing circuit for sensing electrical activity of the patient's heart. The sensing circuit includes a sense amplifier electrically connected in a manner, wherein a polarity of an amplitude of the sensed signal corresponding to an evoked response is opposite a polarity of an amplitude of the sensed signal corresponding to afterpotential. The sensing circuit further includes a band pass filter having a single high pass pole.
