Abstract
An implantable cardiac stimulating device has a pacing circuit connected via an electrode lead system to a first electrode which stimulates and detects activity in the left ventricle, a second electrode to stimulate and detect activity in the right atrium, and to a third electrode to detect activity in the left atrium. Upon the occurrence of a paced or sensed depolarization of the right atrium, a first AV-delay is started. When the subsequent left atrial depolarization is detected, a new AV-interval is started that is optimized for the left side of the heart. Either the left ventricle only, or both ventricles, is paced at the optimized left side AV-interval.
