Synergistic Effects between Phosphorylation of Phospholamban and Troponin I Promote Relaxation at Higher Heart Rate

Figure 4

Percentage increases in ±dP/dtmax and TR75 under combined effect of the pacing and ISO. (a) The percentage increases in ±dP/dtmax between the pacing of 420 beats/min and intrinsic heart rate without and with ISO treatment. (b) The percentage shortenings in TR75 between the pacing of 420 beats/min and intrinsic heart rate without and with ISO treatment. Data are mean ± SEM, hearts for each ISO concentration in each group. * or **   versus baseline.
