Two patients admitted to hospital because syncope and chest pain are presented. In both patients, hyperventilation test caused severe myocardial ischaemia (ST segment elevation) and sudden development of presyncopal sustained ventricular tachycardia which immediately responded to intravenous nitroglycerin. The relationship between coronary vasospasm and sudden death secondary to polymorphic ventricular tachycardia is discussed. Also, the usefulness of the hyperventilation test to detect this problem and to monitor its therapeutic response is addressed.
本文介绍了两名因晕厥和胸痛入院的患者。在这两名患者中，过度通气试验均引发了严重的心肌缺血（ST段抬高）以及晕厥前期持续性室性心动过速的突然发作，静脉注射硝酸甘油后症状立即缓解。文中讨论了冠状动脉痉挛与多形性室性心动过速继发猝死之间的关系。此外，还探讨了过度通气试验在检测该问题及其治疗反应监测方面的作用。
