DEVICE AND METHOD FOR DETERMINING A FREQUENT PRESENCE CRITERION OR EXTRA-SYS- TEM (AURICULAR OR VENTRICULAR) GRAVITY

摘要

The active implantable medical device according to the invention comprises means for detecting the signals of cardiac activity in at least one cardiac cavity, means for detecting the occurrence of extra-systoles, means for assigning a first weighting at each detection of an extra-systole, an extra-systolic counter having at least one counting threshold, means for incrementing the counter-systole counter to the detection of each extra-systole with the weighting associated with it, means of decrementation at each cardiac cycle of the extra-systolic counter in the absence of extra-systole with a second associated weighting. / P
