2 results about "Ventricular stimulation" patented technology

The invention relates to an implantable medical device for stimulating a human or animal heart, the device comprising a single electrode (20) comprising a proximal electrode pole (213) designed and arranged to be implanted within an atrium (2) of the heart (1) to be stimulated and a distal electrode pole (203) designed and arranged to be implanted within a septum (13) of the heart (1) to be stimulated. During operation, the implantable medical device performs the following steps: a) detecting (500) an intrinsic atrial contraction of the heart (1) to be stimulated with the proximal electrode pole (213) or stimulating (500) the atrium (2) of the heart (1) to be stimulated with the proximal electrode pole (213); b) detecting (530) an intrinsic ventricular contraction of the heart (1) to be stimulated with the distal electrode pole (203); c) determining (530) an intrinsic atrioventricular conduction time between i) the intrinsic atrial contraction or the stimulation of the atrium and ii) the intrinsic ventricular contraction; d) setting (550) a stimulated atrioventricular conduction time for stimulating a ventricle (3, 5) of the heart (1) to be stimulated with the distal electrode pole (203), the stimulated atrioventricular conduction time being shorter than the intrinsic atrioventricular conduction time.
