Heart rhythm and conductivity disorders, developing during anginal attacks, and their relation to the pattern of myocardial ischemia have been studied, using 24-hour ECG monitoring, in 60 patients with stable angina, and in 67 patients with unstable angina. Heart rhythm and conductivity disorders at the ventricular level were much more common in Prinzmetal's angina (73%), as compared to the attacks involving ST depression (10%). Their incidence depended both on the direction and magnitude of ST displacement. The probability of supraventricular arrhythmias was unrelated to the magnitude and direction of ST displacement. They tended to develop during the attacks, accompanied by slanting ST depressions (43%) rather than flat ones (8%). Arrhythmias were considerably more common as a complication of the attacks of unstable angina (42%) rather that stable angina (15%) owing to more severe myocardial ischemia.
采用24小时心电图监测，对60例稳定型心绞痛患者和67例不稳定型心绞痛患者进行了研究，观察心绞痛发作时出现的心律和传导紊乱及其与心肌缺血类型的关系。与ST段压低的发作（10%）相比，普林兹金属型心绞痛时心室水平的心律和传导紊乱更为常见（73%）。其发生率既取决于ST段移位的方向，也取决于其幅度。室上性心律失常的发生概率与ST段移位的幅度和方向无关。它们倾向于在伴有ST段斜形压低（43%）而非水平压低（8%）的发作期间出现。由于心肌缺血更严重，心律失常作为不稳定型心绞痛发作（42%）的并发症比稳定型心绞痛发作（15%）更为常见。
