Abstract
A device including circuits able to control the switching of a AAI mode in a DDD mode, and conversely the return of DDD mode to AAI mode, according to predetermined criteria of detection of atrio-ventricular block (AVB) of the first, second, or third degree and of ventricular pause. The device includes moreover circuits for detecting state, able to diagnose at least a specific temporary state of the patient, in particular a state of effort or sleep, and the circuits for mode switching operate in response to these circuits for detecting state to modify selectively, for the length of time when the aforementioned state is diagnosed, the criteria of switching from AAI mode towards DDD mode and/or the criteria of return to AAI mode, and/or the criteria of final commutation in DDD mode.
