目的:探讨右心室梗死心电图诊断的敏感性及意义。方法:对53例急性下壁心肌梗死合并右心室梗死的心电图进行回顾性分析。结果:合并右心室梗死的心电图显示:左胸V1～V5ST段抬高呈递减性,其中V1导联ST段抬高≥1mm15例;Ⅰ、avL、V5、V6导联q波消失10例;添加右胸导联,V3R～V4RST段抬高≥1mm18例,V3R～V6RST段抬高≥1mm21例。结论:右胸导联特别是V3R～V6RST段抬高是诊断右心室梗死的有力证据,当心电图急性下壁心肌梗死并有V1导联ST段抬高,高侧壁及侧壁导联q波消失,及时加做右胸导联对诊断右心室梗死具有较高的敏感性及临床意义。
Objective: To investigate the sensitivity and significance of electrocardiogram diagnosis of right ventricular infarction. Methods: 53 cases of acute inferior myocardial infarction with right ventricular infarction ECG were retrospectively analyzed. Results: The electrocardiogram of right ventricular infarction showed that the elevation of V1 ~ V5ST in the left chest showed a decreasing trend, in which the ST segment elevation of V1 lead was 15mm in 1 case, the disappearance of q wave in Ⅰ, avL, V5 and V6 leads, Right chest lead, V3R ~ V4RST segment elevation ≥ 1mm18 cases, V3R ~ V6RST segment elevation ≥1mm21 cases. Conclusion: The right chest lead, especially V3R ~ V6RST segment elevation is a strong evidence to diagnose right ventricular infarction. When the electrocardiogram acute inferior myocardial infarction with V1 lead ST segment elevation, high side wall and side wall lead q wave Disappear, promptly added right chest lead in the diagnosis of right ventricular infarction has a high sensitivity and clinical significance.
