when extraneuronal uptake inhibitors such as normetanephrine ( 100 mumol/l ) , 3-o-methylisoprenaline ( 100 mumol/l ) or phenoxybenzamine ( 1 mumol/l ) were added to the perfusion fluid containing 3h-isoprenaline ( 1 mumol/l ) and tropolone ( 100 mumol/l ) , the accumulation of isoprenaline was significantly decreased , the incidence of ventricular fibrillation was significantly reduced and the duration of ventricular fibrillation was significantly shortened .
