The informative value of programmed ventricular pacing (PVP), Holter monitoring (HM), and bicycle ergometry (BEM) in the diagnosis of myocardial electric instability was assessed in various clinical types of angina pectoris. An examination was made of 20 patients with first exercise-induced angina (FEIA), 33 with progressive exercise-induced angina (PEIA), 17 with spontaneous angina (SA), 30 with stable exercise-induced angina (SEIA), and postinfarction angina. Myocardial electric instability was estimated from HM and BEM findings in patients with FEIA, SA, as well as in PEIA, SEIA in the presence of preserved myocardial contractility as evidenced by ventriculography. A clear-cut correlation was found between transient myocardial ischemia and the occurrence of high-grade ventricular arrhythmias for the patients from the above-mentioned groups. Lower myocardial contractility despite the nature of angina is an indication for PVP.
在各类临床类型的心绞痛中，评估了程控心室起搏（PVP）、动态心电图监测（HM）和运动平板试验（BEM）对心肌电不稳定诊断的信息价值。对20例初发型劳力性心绞痛（FEIA）患者、33例进行性劳力性心绞痛（PEIA）患者、17例自发性心绞痛（SA）患者、30例稳定型劳力性心绞痛（SEIA）患者以及心肌梗死后心绞痛患者进行了检查。根据HM和BEM结果评估FEIA、SA患者以及PEIA、SEIA患者（心室造影显示心肌收缩功能正常）的心肌电不稳定情况。在上述组别的患者中，发现短暂性心肌缺血与高级别室性心律失常的发生之间存在明确的相关性。无论心绞痛的类型如何，心肌收缩功能降低均提示需进行PVP。
