摘要

目的探讨非典型心室预激心电图特点及临床意义。方法选择我院2018年6月至2020年10月体检中心健康查体发现的非典型心室预激患者28例进行分析

其中10例在每年查体中有心室预激消失的情况发生

将这10例患者作为对照组

剩余18例作为观察组

分析两组患者的心电图。结果通过对28例非典型心室预激进行分析

结果发现其中10例曾记录到正常心电图。非典型心室预激表现为PR间期≥0.10s

平均0.12s左右

QRS波起始部圆墩或模糊切迹

Ⅱ、Ⅲ、aVF、V4-V6导联q波消失

QRS波稍增宽

时限平均0.11s左右。预激波除影响QRS波的起始部形态外

其对R波上升支的坡度影响不大

ST-T可有轻度改变。结论通过对非典型心室预激分析

其QRS波的波形具有一定的特点

通过综合分析能提高对旁道的诊断

具有一定的临床意义。

Abstract

Objective To investigate the characteristics and the clinical significance of atypical ventricular pre-excitation electrocardiogram（ECG）. Methods We chose 28 cases of atypical ventricular pre-excitation in the physical examination center of our hospital from June 2018 to October 2020. In the 28 patients

transit absent of the ventricular pre-excitation was found in 10 cases

and normal ECG had been recorded in each year’s physical examination. Results We analyzed the ECG of 28 cases of atypical ventricular pre-excitation and compared them to10 cases with normal ECG. The PR interval of atypical ventricular pre-excitation was more than 0.10 s. The average QRS duration was about 0.12 s. The Q wave was absent in leads Ⅱ

Ⅲ

a VF and V4-V6

and the QRS wave widened slightly with an average duration of 0.11 s. The ventricular pre-excitation had almost no effect on the slope of the ascending branch of R wave

but little effect on the ST-T segment except the initial part of QRS complex.Conclusions Through the analysis of atypical ventricular pre-excitation

the QRS waveform has certain characteristics

and the comprehensive analysis can improve the diagnosis of bypass

which has certain clinical significance.
