| 摘 要： | 目的探讨I、AVL、V5、V6导联Q波消失对急性下壁伴右室心肌梗死的诊断价值.方法观察73例急性下壁心肌梗死患者的心电图.结果 35例急性下壁伴右室梗死患者中有18例I、AVL、V5、V6导联Q波同时消失,占51.42%,而38例不伴右室梗死患者,仅有1例I、AVL、V5、V6导联Q波消失,占2.63%,差异有非常显著性 (P<0.01).以I、AVL、V5、V6导联Q波消失作为急性下壁伴右室梗死的诊断指标的敏感性为51.42%,特异性为97.36%.结论I、AVL、V5、V6导联Q波同时消失对急性下壁伴右室梗死具有较高的诊断价值.

| Abstract: | Objective: To observe Q wave disappearance in I, aVL, V 5 and V 6 leads for diagnosing right ventricular involvement in acute inferior myocardial infarction (AIMI). Methods: The electrocardiogram of 73 patients with AIMI were observed.Results: Q wave disappearance in above-mentiond leads was more commom in group I than that in group II (51.42% vs 2.63%, P<0.01). Its diagnosing sensitivity and specificity for right ventricular involvement in AIMI was 51.42% and 97.36%, respectively. Conclusion: Q wave disappearance in I, aVL, V 5 and V 6 leads is quite valuable for the diagnosis of right ventricular involvement in AIMI. |
