ABSTRACT:
A pacing method and apparatus includes providing an AV interval initiated by occurrence of either an atrial paced or sensed event. A ventricular safety pacing window is defined. In one embodiment, ventricular events are sensed at only one ventricular side and if a ventricular event is sensed during the ventricular safety pacing window, then a commitment is made to delivery of ventricular stimulus only to the one ventricular side of the patient's heart where the ventricular event is sensed. Further, in another embodiment, sensing of ventricular events may occur at both ventricular sides during the ventricular safety pacing window. If a ventricular event is sensed during the ventricular safety pacing window at a first ventricular side, then commitment is made to delivery of ventricular stimulus to at least the first ventricular side. Further, upon such sensing, modification is provided to reduce the likelihood of sensing ventricular events at the second ventricular side for a predetermined time period following the sensing of the ventricular event at the first side.
