Using echocardiography (ECHO) as the reference method, the aim of this study was to determine the sensitivity, specificity, and predictive value of the electrocardiogram (ECG) in detection of left ventricular hypertrophy (LVH) in patients with aortic stenosis. Forty-one patients, 18 men and 23 women aged 25-80 years (mean 49 years) with uncomplicated aortic stenosis were studied. ECG-LVH was estimated by standard fixed voltage criteria. ECHO-LVH was defined according to left ventricular mass (LV mass) calculated by the Penn method. In the total material, the correlation between ECG-LVH and ECHO-mass was poor (r = 0.56, p < 0.05). The sensitivity and specificity of the ECG was respectively 50% and 100%. The positive predictive value of the ECG in detection of LVH was high (100%). We conclude that the sensitivity of the ECG in detection of LV hypertrophy is unsatisfactorily low. Accordingly, it is recommended that echocardiography be performed in all patients suspected of aortic stenosis.
本研究以超声心动图（ECHO）作为参考方法，旨在确定心电图（ECG）检测主动脉瓣狭窄患者左心室肥厚（LVH）的敏感性、特异性和预测价值。研究对象为41例年龄在25至80岁（平均49岁）、患有单纯性主动脉瓣狭窄的患者，其中男性18例，女性23例。通过标准固定电压标准评估心电图左心室肥厚（ECG-LVH）。根据Penn法计算的左心室质量（LV质量）定义超声心动图左心室肥厚（ECHO-LVH）。在全部研究对象中，ECG-LVH与ECHO质量之间的相关性较差（r = 0.56，p < 0.05）。心电图的敏感性和特异性分别为50%和100%。心电图检测LVH的阳性预测值较高（100%）。我们得出结论，心电图检测左心室肥厚的敏感性低得令人不满意。因此，建议对所有疑似主动脉瓣狭窄的患者进行超声心动图检查。
