Abstract

OBJECTIVE

To investigate the prevalence of Epsilon wave in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC).

METHODS

The epsilon wave was detected in 32 patients [24 men, mean age (42.3 +/- 13.3) years] with ARVC using three different electrocardiography (ECG) recording methods: standard twelve leads ECG (S-ECG), right precordial leads ECG (R-ECG) and Fontaine bipolar precordial leads ECG (F-ECG). The Epsilon wave was defined as wiggler, small spike wave and smooth potential between the end of the QRS complex and the beginning of the ST segment.

RESULTS

Epsilon wave was detected in 37.5%, 37.5% and 50.0% patients with ARVC by S-ECG, R-ECG and F-ECG respectively. The detection rates derived from the three recording methods were similar (P > 0.05). The Epsilon wave was only detectable by S-ECG in one case, by R-ECG in three cases, and by F-ECG in five cases. The detection rate of Epsilon wave was 50.0% by combined use of S-ECG and R-ECG (SR-ECG), 56.3% by combined use of S-ECG and F-ECG (SF-ECG), and 65.6% by combined use of the three recording methods (SRF-ECG). The detection rate was significantly higher by SF-ECG (56.3%) and SRF-ECG (65.6%) than by S-ECG alone (37.5%, all P < 0.05). Most Epsilon waves detected by the S-ECG, R-ECG and F-ECG were small spiked waves.

CONCLUSION

Combined use of S-ECG, F-ECG and R-ECG could increase the detection rate of Epsilon wave in patients with ARVC.

摘要

目的

探讨致心律失常性右室心肌病（ARVC）患者中Epsilon波的发生率。

方法

采用三种不同的心电图（ECG）记录方法，即标准12导联心电图（S-ECG）、右胸导联心电图（R-ECG）和Fontaine双极胸导联心电图（F-ECG），对32例ARVC患者[24例男性，平均年龄（42.3±13.3）岁]进行Epsilon波检测。Epsilon波定义为QRS波群终末与ST段起始之间的摆动波、小棘波和平滑电位。

结果

S-ECG、R-ECG和F-ECG检测ARVC患者Epsilon波的发生率分别为37.5%、37.5%和50.0%。三种记录方法的检测率相似（P>0.05）。Epsilon波仅在1例中通过S-ECG检测到，3例中通过R-ECG检测到，5例中通过F-ECG检测到。S-ECG和R-ECG联合使用（SR-ECG）时Epsilon波的检测率为50.0%，S-ECG和F-ECG联合使用（SF-ECG）时为56.3%，三种记录方法联合使用（SRF-ECG）时为65.6%。SF-ECG（56.3%）和SRF-ECG（65.6%）的检测率显著高于单独使用S-ECG（37.5%，所有P<0.05）。S-ECG、R-ECG和F-ECG检测到的大多数Epsilon波为小棘波。
