Abstract

BACKGROUND AND OBJECTIVES

It is important to analyze right-sided chest electrocardiograms (ECGs) to rule out combined right ventricular infarction in patients with inferior wall infarction. However, the patterns of right-sided chest ECGs in healthy adults have not been thoroughly investigated. This study was conducted to analyze the normal patterns of ECGs and the prevalence of ST segment elevation (STE) in the right-sided precordial leads (V3R and V4R) in healthy adult Koreans.

SUBJECTS AND METHODS

One hundred thirty healthy male volunteers who registered at the Armed Forces Daejeon Hospital for military recruitment were enrolled between December 2006 and April 2007. Standard 12-lead ECGs and right-sided precordial ECGs were obtained. The characteristic features of the QRS complex configuration, STE, and T wave morphology from right-sided precordial ECGs were analyzed.

RESULTS

The most common QRS configuration in right-sided precordial leads was the rS pattern. The Q waves were present in lead V4R in 4.6% of the study population. STEs of 0.5-1 mm were present in 25.4% of V3R recordings and 6.2% of V4R recordings. T waves were usually negative in the right-sided precordial leads. However, if there was a STE in V4R, the associated T waves were usually positive. There were statistically significant correlations between STEs in V4R and STEs in II, III, aVF, V1, V3, and V6 (p<0.01).

CONCLUSION

The STEs, Q waves, and T wave inversions in the V3R and V4R leads were relatively common findings in young, healthy, Korean adults. However, there were no cases in which there was a STE >/=1 mm and a STE concurrently with a q wave.

摘要

背景与目的

分析右侧胸部心电图（ECG）对于排除下壁梗死患者合并右心室梗死非常重要。然而，健康成年人右侧胸部 ECG 的模式尚未得到彻底研究。本研究旨在分析健康成年韩国人右侧胸导联（V3R 和 V4R）心电图的正常模式和 ST 段抬高（STE）的发生率。

对象与方法

2006 年 12 月至 2007 年 4 月期间，我们招募了在韩国大田市军队医院登记参军的 130 名健康男性志愿者。获取标准 12 导联心电图和右侧胸导联心电图。分析右侧胸导联心电图 QRS 波群形态、STE 和 T 波形态的特征。

结果

右侧胸导联最常见的 QRS 构型是 rS 型。在研究人群中，4.6%的导联 V4R 出现 Q 波。25.4%的 V3R 记录和 6.2%的 V4R 记录出现 0.5-1mm 的 STE。右侧胸导联的 T 波通常为负向。然而，如果 V4R 出现 STE，则相关 T 波通常为正向。V4R 的 STE 与 II、III、aVF、V1、V3 和 V6 的 STE 之间存在显著的统计学相关性（p<0.01）。
