两名静息时血管痉挛性心绞痛患者在自发性和麦角新碱诱发的发作期间出现前导联和下导联 ST 段抬高。在这两种情况下，继发于多支冠状动脉痉挛的急性心肌缺血导致可逆性机电分离。冠状动脉造影显示，一例冠状动脉正常，另一例严重三支血管病变；两名患者均出现右冠状动脉痉挛。这些病例表明，血管痉挛性心绞痛患者的冠状动脉痉挛可能同时累及不同动脉并导致缺血性机电分离。对于疑似或确诊多支冠状动脉痉挛的患者，麦角新碱检测是禁忌的。
Two patients with vasospastic angina at rest developed ST segment elevation both in the anterior and inferior leads during spontaneous and ergonovine-induced attacks. In both cases the acute myocardial ischemia secondary to multivessel coronary spasm led to reversible electromechanical dissociation. Coronary arteriography showed normal coronary arteries in one case and severe three-vessel disease in the other; spasm of the right coronary artery was demonstrated in both patients. These cases show that in patients with vasospastic angina coronary spasm may simultaneously involve different arteries and lead to ischemic electromechanical dissociation. Ergonovine testing is contraindicated in those patients with suspected or proved multivessel coronary spasm.
