Table 1 Comparisons of body weight (BW), thickness, wet (WW) and dry weights (DW) of left ventricles (LV) and right ventricles (RV) and area of myocytes between saline-infused hearts (CONT) and isoproterenol-infused hypertrophic hearts (HYP) from rats

From: Increased O2 consumption in excitation–contraction coupling in hypertrophied rat heart slices related to increased Na+–Ca2+ exchange activity
