Values are means ± SE. HR=heart rate, LVDP=left ventricular developed pressure; dP/dtmax=maximum 1st derivative of the change in left ventricular pressure/time; dP/dtmin=minimum 1st derivative of the change in left ventricular pressure/time; Flow rate, coronary flow rate.
p < 0.05 compared with FA group at same time point.
