摘要：
An energy harvester converts into electrical energy the external stresses applied to the implant at the heartbeat rhythm. This harvester includes an inertial unit and a transducer delivering an oscillating electrical signal that is rectified and regulated for powering the implant and charging an energy storage component. The instantaneous variations of this electrical signal are analyzed in a detection window following or preceding a ventricular contraction, to obtain atrial activity information representative of the atrium contribution to the electric signal, in particular information about the presence/absence of a spontaneous atrial contraction, and/or parameters making it possible to determine an atrioventricular delay to be applied if the ventricle has to be stimulated.
