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.
