IMPLANTABLE MEDICAL PACEMAKER AND METHOD FOR OPTIMIZING THE IMPLANT PLACE FOR INTERVENTRICULAR AND ATRIOVENTRICULAR INTERVALS

摘要

The pacemaker has identifying and isolating units for identifying and isolating two components corresponding to endocardial acceleration peaks (PEA1, PEA4) in an endocardial acceleration signal (EA), respectively. A determining unit determines an atrio-ventricular delay (DAV) based on a time parameter related to one of the components, where the delay is calculated for a value of inter-ventricular delay so as to obtain pairs of values of the delays. A selection unit selects one of the pairs of values based on a non-temporal parameter related to the component.
