动态心电图(DCG)已广泛应用于临床,在冠心病的诊断以及对室性心律失常严重程度判断和抗心律失常药物疗效怦价方面起着愈来愈重要的作用。70年代Lown倡导一种心律失常方程式,对心律失常重症度的判断有一定的帮助。但在动态观察及评估抗心律失常药物疗效方面也存在诸多不便,为此,我们设计了一种新的方程式,现报告如下。 Dynamic electrocardiogram (DCG) has been widely used in clinical practice, which plays an increasingly important role in the diagnosis of coronary heart disease and in judging the severity of ventricular arrhythmias and the anti-arrhythmic drug efficacy. In the 1970s, Lown advocated an arrhythmia equation that would help to determine the severity of arrhythmia. However, there are also a lot of inconveniences in dynamically observing and assessing the efficacy of anti-arrhythmic drugs. To this end, we have devised a new equation and are reported as follows.
