预激综合征心电图的基本特征包括P-R间期缩短;QRS间期延长,P-J间期正常;QRS起始部有预激波和常并发室上性快速心律失常等已被人所熟知。但该综合征尚有一些其他表现,有可能导致误诊或漏诊。现就有关预激综合征心电图诊断的一些问题作简要探讨。临床心电图资料本文收集预激综合征患者45例(男34,女11)的 Pre-excitation syndrome ECG basic features include P-R interval shortening; QRS interval prolongation, P-J interval is normal; QRS start with pre-shock and often complicated supraventricular tachyarrhythmias have been known. However, there are some other manifestations of the syndrome, which may lead to misdiagnosis or missed diagnosis. Now on the pre-excitation syndrome ECG diagnosis of some of the issues briefly discussed. Clinical ECG Data This article collected 45 patients with pre-excitation syndrome (male 34, female 11)
