动态心电图(DCG)监测中出现宽型 QRS 波(W-QRS)可见于心律失常的很多类型。但大部分见于室性早搏,其中一些高危性室早常可导致室速、室颤,继而导致心源性猝死。本文资料的分析提示:临床上已明确有器质性心脏病的患者中心律失常发生率甚高,严重的心律失常也较常见,故其心源性猝死的危险性较无器质性心脏病者大得多。通过DCG 监测来评价 W-QRS 的性质、类型、严重程度及预后等都明显优于普通心电图检查,这在临床上是具有重要意义的。
Wide QRS waves (W-QRS) appear in many types of arrhythmia in dynamic electrocardiogram (DCG) monitoring. But most are found in premature ventricular contractions, some of which are often high-risk ventricular can often lead to ventricular tachycardia, ventricular fibrillation, which in turn lead to sudden cardiac death. The analysis of the data in this paper suggests that the incidence of arrhythmia in patients with organic heart disease has been clinically very high, and serious arrhythmia is also common, so the risk of sudden cardiac death is lower than that of non-organic heart disease Much bigger. The quality, type, severity and prognosis of W-QRS evaluated by DCG monitoring are significantly superior to those of ordinary ECG, which is clinically significant.
