in a second experiment performed at 80 mmhg perfusion pressure ( nine study hearts and seven controls ) the increased myocardial flow rate resulted in a higher left ventricular +dp/dt in both groups , but the study hearts still had a lower mean ( sd ) myocardial flow rate than the controls ( 12.5 ( 0.9 ) vs 19.8 ( 2.2 ) ml x g-1 lv weight x min-1 ;
