the electrocardiograms ( ecg ) of 64 subjects who exhibited an echocardiographically demonstrable increase in thickness of the interventricular septum and left ventricular posterior wall ( group 1 , 22 patients ) , isolated left ventricular internal dimension ( group 2,26 patients ) , combined wall thickness and chamber diameter ( group 3 , 2 patients ) , and septal thickness , ( group 4 , asymmetric septal hypertrophy , 14 patients ) were reviewed in order to determine sensitivity of ecg criteria for the diagnosis of left ventricular hypertrophy ( lvh ) proposed in 1949 by sokolow and lyon ( 13 ) , in 1968 by romhilt and estes ( 14 ) , and in 1973 the new york heart association ( 15 ) .
