A group of 36 juvenile hypertensive patients underwent echocardiographic and electrocardiographic examinations. In 15 of them echocardiography detected increased left ventricular posterior wall and/or septal thickness in the diastole. Asymmetric septal hypertrophy with a septum posterior wall ratio greater than 1.3 was established in 7 cases (19%). The ECG abnormalities included signs of left atrial abnormality and voltage criteria after Sokolow-Lyon and McPhie. The sensitivity of electrocardiography in detecting left ventricular hypertrophy determined by echocardiography was 15% after Sokolow-Lyon, 15% after McPhie ad 31% using all the criteria combined. The specificity of ECG was 100, 87 and 87%, respectively. The ECG is less sensitive in left ventricular hypertrophy in younger individuals than in the adult population. This seems to be due to a lower degree of hypertrophy in the early stages of essential hypertension. No significant correlation of echocardiographically determined left ventricular mass with precordial ECG voltage was found.
一组36名青少年高血压患者接受了超声心动图和心电图检查。其中15人超声心动图检测到舒张期左心室后壁和/或室间隔厚度增加。7例（19%）确定为不对称性室间隔肥厚，室间隔与后壁比值大于1.3。心电图异常包括左心房异常体征以及Sokolow-Lyon和McPhie标准后的电压标准。根据Sokolow-Lyon标准，心电图检测经超声心动图确定的左心室肥厚的敏感性为15%，McPhie标准后为15%，综合所有标准后为31%。心电图的特异性分别为100%、87%和87%。与成人相比，心电图对年轻个体左心室肥厚的敏感性较低。这似乎是由于原发性高血压早期肥厚程度较低。未发现超声心动图测定的左心室质量与胸前心电图电压之间存在显著相关性。
