目的探讨缓慢与快速室上性心律失常交替或间歇发生的心电图临床分型及其发生机制。方法选择20例出现上述心电现象的动态心电图(DCG)进行回顾性分析。结果 20例DCG改变可分为3种类型:①慢快综合征15例、快慢综合征2例、变异型快慢综合征3例。三者发生机制、DCG特征、临床治疗及预后均不相同。结论明确三者临床心电图分型及发生机制,对临床治疗选择及预后判断均有极重要意义。
Objective To investigate the clinical classification of electrocardiogram and its mechanism of alternating or intermittent slow and rapid supraventricular arrhythmia. Methods Twenty patients with electrocardiogram (ECG) were retrospectively analyzed. Results 20 cases of DCG changes can be divided into three types: ① slow syndrome 15 cases, fast syndrome 2 cases, variant fast syndrome 3 cases. The mechanism of the three, DCG characteristics, clinical treatment and prognosis are not the same. Conclusions A clear classification of the three clinical ECG and its mechanism of choice for clinical treatment and prognosis are of great significance.
