    • A multi-chamber pacing system has a pulse generator for successively delivering pacing pulses to chambers of a patient's heart. Evoked response detectors having blanking intervals following the delivery of pacing pulses include sensing elements for sensing IEGM-signals from each of the heart chambers and an integrating unit that integrates the IEGM-signal within evoked response detection time windows after delivery of pacing pulses for detecting evoked response. The evoked response detection time window for a heart chamber contain at least one blanking interval resulting from delivery of a pacing pulse to another chamber and each of the sensed IEGM signals having a generally known morphology. An integral reconstructing unit reconstructs the time integral of the IEGM signal from one of the heart chambers in the blanking interval following delivery of a pacing pulse to another heart chamber.
    • 多室起搏系统具有脉冲发生器,用于连续地向患者心脏的腔室输送起搏脉冲。 在递送起搏脉冲之后具有消隐间隔的诱发响应检测器包括用于感测来自每个心室的IEGM信号的感测元件和在递送用于检测诱发的起搏脉冲之后的诱发响应检测时间窗口内积分IEGM信号的积分单元 响应。 心室的诱发反应检测时间窗口包含至少一个消隐间隔,其由将起搏脉冲递送到另一个腔室而产生,每个感测的IEGM信号具有通常已知的形态。 整体重建单元在将起搏脉冲递送到另一个心室之后的消隐间隔中的一个心室重建IEGM信号的时间积分。
