This paper assesses the sensitivity and specificity of the electrocardiogram in detecting left ventricular hypertrophy in 75 hypertensive patients. Each patient underwent a 12 lead electrocardiogram and echocardiogram. Left ventricular mass index, using echocardiogram, was calculated according to the Penn convention and left ventricular hypertrophy was assessed by standard electrocardiographic criteria. The electrocardiogram was found to be very specific but insensitive in the detection of left ventricular hypertrophy as compared with the echocardiogram. Other non-voltage dependent markers appeared to have similar reliability. We conclude that the electrocardiogram may be unreliable in the detection of left ventricular hypertrophy in hypertensive patients. Accurate assessment of left ventricular hypertrophy, in these patients should be by echocardiography.
本文评估了心电图检测75例高血压患者左心室肥厚的敏感性和特异性。每位患者均接受了12导联心电图和超声心动图检查。使用超声心动图根据宾夕法尼亚标准计算左心室质量指数，并通过标准心电图标准评估左心室肥厚。与超声心动图相比，发现心电图在检测左心室肥厚方面特异性很强但敏感性较差。其他非电压依赖性指标似乎具有相似的可靠性。我们得出结论，心电图在检测高血压患者左心室肥厚方面可能不可靠。对这些患者左心室肥厚的准确评估应通过超声心动图进行。
