Abstract

The invention relates to an implantable medical device for stimulating a human or animal heart that comprises a proximal electrode pole (213), a first distal electrode pole (203), and a second distal electrode pole (223). During operation, the implantable medical device performs the following steps: a) detecting (500), with the proximal electrode pole (213), an intrinsic atrial contraction of the heart (1) to be stimulated or stimulating (500), with the proximal electrode pole (213), the atrium (2) of the heart (1) to be stimulated; b) detecting (530), with the first distal electrode pole (203) and with the second distal electrode pole (223), an intrinsic ventricular contraction of the heart (1) to be stimulated; c) determining (530) a first intrinsic atrioventricular conduction time between i) the intrinsic atrial contraction or the stimulation of the atrium and ii) the intrinsic ventricular contraction detected with the first distal electrode pole (203); and determining (530) a second intrinsic atrioventricular conduction time between i) the intrinsic atrial contraction or the stimulation of the atrium and iii) the intrinsic ventricular contraction detected with the second distal electrode pole (223); d) setting (550) a stimulated atrioventricular conduction time for stimulating the ventricle (3, 5) of the heart (1) to be stimulated with the first distal electrode pole (203) and/or the second distal electrode pole (223), the stimulated atrioventricular conduction time being shorter than the shorter of the first intrinsic atrioventricular conduction time and the second intrinsic atrioventricular conduction time.
