79 ECGs, recorded during angina pectoris, from 52 patients were studied to determine the relations of arrhythmias and ST-segment changes and to evaluate the relationship between the prevalence of arrhythmias, the severity of coronary artery disease and left ventricular function. Arrhythmias were found in 22% of the ECGs (VPCs in 9, VT in 4, SVPCs in 3, sinus bradycardia in 1). Angina pectoris attacks accompanied by ST-segment elevation, ST-segment depression or unchanged ST-segment showed disturbances of rhythm in 47%, 24% and 0%. If coronary spasm without significant coronary stenoses was the cause for myocardial ischemia, arrhythmias appeared with 75% more often than in myocardial ischemia caused by organic stenoses (19%). Patients with disturbances of rhythm during spontaneous angina pectoris do not have anymore deterioration in left ventricular function than patients without arrhythmias.
对52例患者在心绞痛发作期间记录的79份心电图进行了研究，以确定心律失常与ST段改变之间的关系，并评估心律失常的发生率、冠状动脉疾病的严重程度与左心室功能之间的关系。在22%的心电图中发现了心律失常（室性早搏9例，室性心动过速4例，室上性早搏3例，窦性心动过缓1例）。伴有ST段抬高、ST段压低或ST段无变化的心绞痛发作中，心律失常的发生率分别为47%、24%和0%。如果无明显冠状动脉狭窄的冠状动脉痉挛是心肌缺血的原因，心律失常出现的频率比由器质性狭窄引起的心肌缺血高75%（19%）。自发性心绞痛发作期间出现心律失常的患者，其左心室功能恶化程度并不比没有心律失常的患者更严重。
