Anatomic and electrocardiographic correlation in combined ventricular hypertrophy
American Heart Journal
1. 1. The precordial and augmented limb leads of seventy-three electrocardiograms from patients with necropsy evidence of combined ventricular hypertrophy have been analyzed. 2. 2. When left ventricular hypertrophy occurred as a result of hypertensive or aortic valve disease, its recognition was slightly impaired by the concomitant right ventricular hypertrophy. Left ventricular hypertrophy associated with cor pulmonale is hidden electrocardiographically. 3. 3. Right ventricular hypertrophy occurring as a result of hypertensive heart disease or mitral disease was masked by the concomitant left ventricular hypertrophy. Cor pulmonale occurring with left ventricular hypertrophy was apparent. 4. 4. The data suggest that rotational effects and the potentials of the respective ventricular walls are both important in the recognition of right ventricular hypertrophy in the presence of left ventricular hypertrophy. The electrocardiographic diagnosis of right ventricular hypertrophy in the presence of left ventricular hypertrophy may be suspected when atypical electrical positions are present, or the transition zone is shifted to the left. 5. 5. The diagnosis of combined ventricular hypertrophy is difficult and was apparent only in ten cases of seventy-three. In these cases, right ventricular hypertrophy was recognized by the rotational changes. © 1953.
