Fig. 2From: Increased O2 consumption in excitation–contraction coupling in hypertrophied rat heart slices related to increased Na+–Ca2+ exchange activityComparison of mean basal metabolic mVO2 and excitation–contraction (E–C) coupling mVO2 between LV slices from HYP (n = 12 sets from 6 hearts) and LV slices from CONT (n = 10 sets from 5 hearts). *P < 0.05 vs. CONT. **P < 0.001 vs. CONT. Upper insets indicated the method for preparing the LV sliceBack to article page
