[Treatment of carotid sinus syncope by demand electro-systolic cardiac pacing].

The observations of 2 patients having carotid sinus syncopes treated by temporary (1 case), or definitive (1 case) endovenous demand cardiac pacing are correlated with 15 similar observations found in the literature. In all these patients, cardiac pacing is more effective than all the other treatments cutting off the hyperactive reflex. Indeed, carotid sinus hypersensibility seems to be good, though unusual indication of cardiac pacing.
