5.5.4.3 AV Repetitive Hysteresis
With AV Repetitive Hysteresis, the AV delay is extended by a defined hysteresis value after sensing
an intrinsic ventricular event. When a ventricular stimulated event occurs, a long AV delay is used for
the programmed number of cycles. (1 … 10). If an intrinsic rhythm occurs during one of the repetitive
cycles, the long duration AV delay interval remains in effect. If an intrinsic rhythm does not occur during
the repetitive cycles, the original AV delay interval resumes.
