abstract：:Intracellular pH (pHi) was measured in left ventricular myocytes from hearts hypertrophied by constriction of the thoracic aorta. There was a continuous relation between an increase in heart-to-body weight ratio and a decrease in pHi (mean +/- S.D., 7.06 +/- 0.18 pH units in control hearts vs. 6.87 +/- 0.17 pH units i...
