A 54-year-old man with mitral valve prolapse syndrome diagnosed by echocardiography complained of anginal pain associated with ventricular tachyarrhythmia. One day he suddenly lost consciousness, and ECG at that time revealed ventricular fibrillation. Thereafter, he developed ST elevation, sporadic premature ventricular contractions, and R on T phenomenon leading to ventricular fibrillation during the attack of anginal pain. His coronary arteriogram was normal. This case implies that coronary artery spasm may be one of the causes of chest pain and ventricular tachyarrhythmias in patients with mitral valve prolapse syndrome.
一名经超声心动图诊断为二尖瓣脱垂综合征的54岁男性，主诉伴有室性快速心律失常的心绞痛。一天，他突然失去意识，当时的心电图显示心室颤动。此后，他在心绞痛发作时出现ST段抬高、散在的室性早搏以及R波落在T波上现象，导致心室颤动。他的冠状动脉造影正常。该病例提示冠状动脉痉挛可能是二尖瓣脱垂综合征患者胸痛和室性快速心律失常的原因之一。
