THE CARDIOGRAPHIC DIAGNOSIS OF COMBINED VENTRICULAR HYPERTROPHY

Abstract
Ecg. signs of combined hypertrophy are likely to be seen in only 25% of cases in which there is hypertrophy of both sides. The association of a vertical heart with signs of left ventricular hypertrophy is highly suggestive of combined hypertrophy. The presence of an R wave greater than Q in AVR, S wave larger than R in V5 with inversion of T in V1 together with signs of left ventricular hypertrophy, is diagnostic of combined hypertrophy. The presence of the ecg. evidence of right ventricular enlargement in addition to those of hypertrophy of the left ventricle due to a left-sided lesion may be a specific sign of rotation and have prognostic value of impending failure of the right ventricle.
