肢体导联室壁激动时间诊断高血压病左心室肥厚的探讨

摘要

目的探讨心电图肢体导联室壁激动时间(VAT)诊断左心室肥厚(LVH)的价值.方法测定116例高血压患者邻近心电轴肢体导联 I、III 的 VAT,与超声心动描记术测定的左心室质量(LVM)进行比较.结果心电图肢体导联 VAT 与LVM 之间呈高度正相关[r=0.88(男性)、0.70(女性),均 P<0.01].肢体导联 VAT ≥0.04s 诊断高血压 LVH 的敏感性(80.1%)显著高于常规心电图标准(22.2%~51.7%)(P<0.01).结论肢体导联 VAT 对高血压 LVH 的诊断有重要意义.%Objective To evaluate the value of ventricular activation time (VAT) in limb leads on ECG in the diagnosis of left ventricular hypertrophy. Methods VAT in lead I and III was measured and compared to left ventricular mass deter-mined by echocardiography in 116 patients with hypertension. Results The VAT was highly correlated with left ventricu-lar mass (r=0.88 in male, r=0.70 in female, P<0.01). The sensitivity of VAT 0.04s in the diagnosis of hypertensive left ven-tricular hypertrophy was significantly higher than that of routine electrocardiographic criteria (80.1% vs. 22.2%~51.7%, P<0.01). Conclusion The VAT in limb leads is of significance for diagnosing hypertensive left ventricular hypertrophy.
