implantable medical device such as pacemaker, with improved control of automatic aai / ddd modusschaltung in presence of atrio ventricular blocks anfallartig

摘要

This device comprises means adapted to control the tilting of an aai mode of a ddd mode, and, conversely, the return of the ddd mode to aai mode, as a function of predetermined criteria of detection of a block atrio - ventricular tachycardia (avb) of the first, second or third degree and ventricular pause. The device further comprises means for detecting state, adapted to diagnose at least one specific state, temporary, of the patient, in particular a state of stress or sleep, and the switching means of which operate in response to the state detecting means for selectively modify, during the time when said state is diagnosed, the criteria of the tilting of the method, aai towards ddd mode and / or the criteria of return to aai mode, and / or the criteria of the final commutation in ddd mode.
