Abstract:
The extended AV interval of an auto intrinsic conduction search of an implantable cardiac stimulation device has premature atrial contraction protection. A timer times a base AV interval and the extended AV interval. If the heart is paced with the extended AV interval and a premature atrial contraction is detected, the extended AV interval is maintained. Once a predetermined number of consecutive premature atrial contractions are detected, the extended AV interval is reset to the base AV interval.
