目的探讨中国正常人ECG-Cornell标准及其在高血压左室肥厚中的诊断价值。方法以彩色多普勒超声心动图左室质量指数(UCG-LVMI)为依据,对110例中国正常人进行UCG-LVMI检测;心电图Ravl和SV3参数反复测三个心动周期,取均值。ECG Cornell电压值,按95%正常值范围(x-±1.64s)上限值确立本研究Cornell电压的中国人标准。结果国人Cornell电压:男性>24mm、女性>20mm作为ECG-LVH的新界值。Cornell电压新标准在正常组和LVH组间存在显著性差异(P<0.001)。结论国人Cornell电压标准与国外有异,对高血压左室肥厚诊断具有重要意义。
Objective To investigate the ECG-Cornell criteria of normal Chinese and its diagnostic value in hypertensive left ventricular hypertrophy. Methods Based on the color Doppler echocardiography of left ventricular mass index (UCG-LVMI), UCG-LVMI was detected in 110 Chinese normal subjects. The electrocardiogram Ravl and SV3 parameters were measured repeatedly for three cardiac cycles and the mean was taken. ECG Cornell voltage value, the 95% normal range (x- ± 1.64s) upper limit to establish the Cornell voltage Chinese standard. Results Cornell voltage: male> 24mm, female> 20mm as a new threshold of ECG-LVH. Cornell voltage new standard in the normal group and LVH group there was a significant difference (P <0.001). Conclusion Chinese Cornell voltage standards and abroad are different, the diagnosis of hypertension with left ventricular hypertrophy is of great significance.
