    摘要： Methods and systems for classifying cardiac responses to pacing stimulation and/or preventing retrograde cardiac conduction are described. Following delivery of a pacing pulse to an atrium of the patient's heart during a cardiac cycle, the system senses in the atrium for a retrograde P-wave. The system classifies the atrial response to the pacing pulse based on detection of the retrograde P-wave. The system may also sense for an atrial evoked response and utilize the atrial evoked response in classifying the cardiac pacing response. If capture is not detected, the system may deliver additional atrial pacing pulses to reduce atrial retrograde conduction. A backup pace may be delivered to prevent the atrial retrograde conduction if an atrial evoked response is not detected during a cardiac cycle. Alternatively, retrograde management may involve delaying a next scheduled pace may be until expiration of an atrial effective refractory period.

    摘要： Methods and systems for performing capture threshold tests are described. During an initialization procedure a capture detection interval and capture detection threshold are determined based on peak values of cardiac signals sensed following the supracapture threshold initialization pulses. Following initialization, a plurality of pacing pulses to the atrium are delivered and the peak values of the cardiac signals sensed following each of the plurality of pacing pulses are determined. The peak values are compared to the pacing artifact threshold and the capture detection threshold. A timing of each of the peak values is compared to the capture detection interval. For each pacing pulse, discrimination between a captured response, a noncaptured response, and a fusion response is based on the peak value and timing comparisons.

    摘要： Methods and systems for classifying cardiac responses to pacing stimulation and managing retrograde conduction and pacemaker mediated tachyarrhythmia are described. An atrial pacing pulse and a ventricular pacing pulse are delivered during a paced cardiac cycle. A post ventricular atrial refractory period (PVARP) is timed following the ventricular pacing pulse. The system determines if the atrial pacing pulse captures the atrium. An atrial depolarization occurring after the paced cardiac cycle is sensed. Retrograde management is initiated if the atrial pacing pulse did not capture the atrium and the atrial depolarization occurred during the PVARP. Pacemaker mediated tachyarrhythmia (PMT) is initiated if the atrial pacing pulse did not capture the atrium and the atrial depolarization did not occur during the PVARP.
