心绞痛是临床常见的症侯,主要是由冠状动脉硬化,心肌缺血、缺氧所引起的。临床上心电图的变化可反映心肌缺血的程度,因为心电图的ST段和T波代表心室的复极过程,故可从ST段和T波的改变观察各种类型的暂时性心肌缺血。但仅靠常规心电图观察,有其局限性,易造成漏诊。对患者进行连续动态心电监测,能及时发现心绞痛发作期间ST段改变,观察心肌缺血的程度,对临床诊断和治疗具有重要意义。我们科自1987年以来,对35例心绞痛患者进行了心电监护。现介绍如下。
Angina is a common clinical symptoms, mainly caused by coronary atherosclerosis, myocardial ischemia, hypoxia. Changes in clinical ECG can reflect the degree of myocardial ischemia, ECG ST segment and T wave on behalf of ventricular repolarization process, it can be observed from the ST segment and T wave changes of various types of transient myocardial ischemia. But only by conventional ECG, has its limitations, easily lead to missed diagnosis. Continuous dynamic ECG monitoring of patients, timely detection of ST segment changes during angina pectoris, to observe the extent of myocardial ischemia, clinical diagnosis and treatment is of great significance. Since 1987, our department has enrolled 35 patients with angina pectoris. Now introduced as follows.
