Abstract
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.
