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

<table>Percentage increases in ±dP/dt<sub>max</sub> and TR<sub>75</sub> under combined effect of the pacing and ISO. (a) The percentage increases in ±dP/dt<sub>max</sub> between the pacing of 420 beats/min and intrinsic heart rate without and with ISO treatment. (b) The percentage shortenings in TR<sub>75</sub> between the pacing of 420 beats/min and intrinsic heart rate without and with ISO treatment.
