device and method for the determination of a time criterion of presence or severity of extra systole (atrial or ventricular)

摘要

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