QRS-complex and ST-segment were analyzed by ECG using 12 routine leads in three right chest wall leads (V3R, V4R, V5R) in patients with chronic anterior wall myocardial infarction. A QRS-complex was found in leads V3R and V4R in proximal occlusion of the LAD in all (n = 22) but four patients, where retrograde filling of the septal branch of the LAD was observed. When the medial LAD was occluded (n = 13), rS-complex was present in the right chest wall leads. Similar ECG findings were revealed in normal coronary arteries (n = 46). QS-complex in leads V3R and V4R refers to right ventricle infarction in the chronic phase of anterior wall myocardial infarction, when the proximal LAD is occluded.
采用心电图分析慢性前壁心肌梗死患者12条常规导联及三个右胸壁导联（V3R、V4R、V5R）的QRS波群和ST段。在所有患者（n = 22）中，除4例观察到LAD间隔支逆行充盈的患者外，LAD近端闭塞时V3R和V4R导联可发现QRS波群。当LAD中段闭塞时（n = 13），右胸壁导联出现rS波群。正常冠状动脉患者（n = 46）也有类似的心电图表现。V3R和V4R导联出现QS波群提示前壁心肌梗死慢性期近端LAD闭塞时合并右心室梗死。
