[Prinzmetal's variant form of angina pectoris occurring with ventricular tachycardia, ventricular flutter and fibrillation].

After a brief literature survey, the author described a patient of 42, with its first stenocardia paroxysm, accompanied by tachycardia, clonic-tonic convulsion as MAS syndrome, loss of consciousness and spontaneous restoration. After 6 hours a second stenocardia paroxysm followed, when a gigantic ST segment elevation was recorded in precordial leads, appearance of paroxysmal ventricular tachycardia, ventricular fibrillation, loss of consciousness, restored via defibrillation. ST elevation faded by the 25 the minute. The changes are stressed to be most likely due to coronary spasm of r. descendens of the left coronary artery and to changes in the small myocardial vessels. The opinion that Prinzmetal stenocardia is a variant of angina pectoris is confirmed as well as that paroxysm could be with a lethal end due to ventricular fibrillation.
