目的探讨左室肥厚心肌质量指数与心电图Cornell电压的关系。方法检测90例中国高血压左室肥厚患者心脏质量指数(UCG-LVMI),心电电压各参数反复测三个心动周期,取均值,评价高血压左室肥厚心脏质量指数与ECG-Cornell电压与的关系。结果 ECG-LVH阳性对应的UCG-LVMI间无显著性差异(P(0.05)。各项ECG电压与UCG-LVMI具有一定程度的相关性,以Cornell电压与UCG-LVMI相关性最佳(r=0.832 P(0.001)。伴ST-T改变(劳损)的综合电压与UCG-LVMI间相关性更高,尤以Cornell电压最为突出(r=0.928 P(0.001)。结论高血压左室肥厚心肌质量指数(UCG-LVMI)与ECG-Cornell电压呈明显相关性,ECG-Cornell电压对高血压左室肥厚的诊断具有重要价值。
Objective To investigate the relationship between left ventricular hypertrophy and Cornell voltage. Methods Ninety patients with hypertensive left ventricular hypertrophy in China were enrolled in this study. The cardiac mass index (UCG-LVMI), ECG parameters were measured repeatedly for three cardiac cycles, and the mean values of left ventricular hypertrophy and ECG-Cornell voltage and Relationship. Results There was no significant difference (P (0.05) between ECG-LVH positive UCG-LVMI and ECG-LVG.Cornell voltage had the best correlation with UCG-LVMI (r = 0.832 P (0.001) .Compared with UCG-LVMI, the combined voltage of ST-T changes (strain) had higher correlation, especially the Cornell voltage was the most prominent (r = 0.928 P The index (UCG-LVMI) is significantly correlated with the ECG-Cornell voltage and the ECG-Cornell voltage is of great value in the diagnosis of hypertensive left ventricular hypertrophy.
