在 Prinzmetal 所描写的变异型心绞痛患者中,近半数在 ST 段抬高期间有心律失常出现,以室性心律失常为多见。自发变异型心绞痛发作时出现严重心律失常和心脏阻滞常预示以后有猝死可能,故有重要临床意义。由于自发变异型心绞痛发作无法预测,因此对发作时的心律失常分析也较困难。鉴于自发性和麦角新碱诱导发作的变异型心绞痛在临床及血管造影上的特征很相似,本文用麦角新碱诱导变异型心绞痛发作来了解发作期间室性心律失常的发生率、严重性及其与临床的关系,并与自发性发作 Nearly half of patients with variant angina described by Prinzmetal have arrhythmias during ST elevation and are more common with ventricular arrhythmias. Spontaneous variant angina pectoris occurs when severe arrhythmia and heart block often indicates the possibility of sudden death, it has important clinical significance. Because of the unpredictable nature of spontaneous variant angina attacks, it is also difficult to analyze arrhythmias at the time of the episode. In view of the spontaneous and ergometrine induced angina pectoris in clinical and angiographic characteristics of the very similar, this article ergometrine induced angina pectoris onset to understand the onset of ventricular arrhythmias, the severity and its Relationship with the clinic and with spontaneous seizures
