Abstract:
An active implantable medical device comprising:means for detecting events of spontaneous electrical activity in a cardiac cavity;means for delivering a stimulation to said cardiac cavity, said means having an actual escape interval wherein said delivering means comprises means for delivering a stimulation to the cavity during a cardiac cycle if no spontaneous event is detected at the end of a time corresponding to the end of a period of said actual escape interval since the last detected spontaneous event or stimulation in said cavity;means for counting a predetermined number of successive stimulated events,means for discriminating between spontaneous events detected in the cavity of an extrasystole origin and a non-extrasystole origin, andmeans for modifying the actual escape interval at each cardiac cycle in a manner to reduce by a first programmable value the actual escape interval after detection of a spontaneous event of non-extrasystole origin, and to increase by a second programmable value the actual escape interval after delivery of a predetermined number of successive stimulations.
