[Sudden syncope and myocardial ischemia. Apropos of a case].
It is unusual to carry out a systematic search for myocardial ischemia in patients who have suffered a sudden syncopy with no known history of angina. We report a case involving loss of consciousness (LC) in the context of sub-hissian atrioventricular block (AVB) which required the installation of a pacemaker, with the detection of angina pectoris immediately after its installation. Coronary artery angiography confirmed a diagnosis of severe, multitrunk coronary disease characterized by a tight stenosis of the common trunk. If consciousness is lost by a patient suffering from baseline conduction impairment with no chest pain, the first thought is 3rd degree degenerative paroxysmal AVB but the possibility of an ischemic origin of this AVB should not be overlooked.
