Electrocardiographic diagnosis of left ventricular hypertrophy by the time-voltage integral of the QRS complex.


OBJECTIVES This study was conducted to test the hypothesis that the time-voltage integral of the QRS complex can improve the electrocardiographic (ECG) identification of left ventricular hypertrophy. BACKGROUND Standard ECG criteria have exhibited poor sensitivity for left ventricular hypertrophy at acceptable levels of specificity. However, left… (More)
