    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, wherein the sensing circuit includes a dedicated evoked response sense amplifier and at least one high pass coupling capacitor electrically connected as a portion of a high pass network and between a pacing/sensing electrode and a blanking switch. A plurality of high pass coupling capacitors are coupled in parallel each having a separate blanking switch, thereby creating a differential network to offset imbalance sensed from the electrode due to extraneous factors.

    摘要： An implantable cardiac rhythm management device capable of automatically detecting intrinsic and evoked response of a patient's heart and suitable for use during capture verification. The device of the present invention may operate in an automatic capture verification mode, wherein an electrocardiogram signal of a patient's heart is received and used by the device to determine whether a stimulation pulse evokes a response by the patient's heart. The device suspends the automatic capture verification mode and/or adjust the detection threshold dependent upon detected and/or measured noise, a determined amplitude of evoked response, a determined modulation in the evoked response, or detected and/or measured artifact. Further, the sensing circuit of the rhythm management device of the present invention reduces afterpotentials that result due to delivery of the stimulation pulses.

    摘要： 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.
