摘要
比较ECG的Sokolow-lyon标准和Cornell标准对诊断左室肥厚的敏感性和特异性,以评价其在高血压左室肥厚(Left Ventricular Hypertrophy,LVH)中的诊断价值。对188例高血压患者,根据超声心动图(Ultrasoniccardiogram,UCG)检查结果有无LVH分组,分别计算Sokolow-lyon标准和Cornell标准以及两种标准联用时诊断LVH的敏感性、特异性及准确性,结果显示Sokolow-lyon标准诊断LVH敏感性为28.6%,特异性为96.1%,准确性为55.9%;Cornell标准诊断的敏感性为40.1%,特异性为97.4%,准确性为63.2%;两者联用的敏感性为51.8%,特异性为98.7%,准确性为70.7%。结果提示ECG诊断LVH特异性高,敏感性差,Cornell标准敏感性高于Sokolow-lyon标准,两种方法联合应用可提高LVH的检出率。
To evaluate the sensitivity and the specificity of diagnosis of left ventricular hypertrophy by ECG between Sokolow-lyon criteria and Cornell criteria, 118 cases of hypertensive left ventricular hypertrophy were examined by ECG （Electrocardiogram, ECG） and UCG（Ultrasonic cardiogram, UCG）. It was divided into two groups including both left ventricular hypertrophy group and non left ventricular hypertrophy group by UCG,and then the sensitivity and the specificity and the accuracy was calculated individual including Sokolow-lyon criteria and Cornell criteria and Sokolow-lyon criteria plus Cornell criteria. The results that the sensitivity of Sokolow-lyon criteria and Cornell criteria and Sokolow-lyon cri- teria plus Cornell criteria for detecting left ventricular hypertrophy was 28.6 % and 40.1% and 51.8%,the specificity was 96.1% and 97.4% and 98.7% ,the accuracy was 55.9% and 63.2% and 70.7%. So the specificity is higher than the sensitivity for detecting left ventricular hypertrophy by ECG, the sensitivity of Cornell criteria is higher than of Sokolow-lyon criteria and Sokolow-lyon criteria plus Cornell criteria can improve to detect the percentage of left ventricular hypertro- phy.
