comparison of these drugs in fibrillating hearts on cardiopulmonary bypass showed that epinephrine increased the `` '' vigor of fibrillation '' '' ( intraventricular balloon pressure rose 24 percent and oxygen uptake increased 42 % ) but impeded subendocardial flow 53 % ( endocardial/epicardial flow ratio fell from 0.79 to 0.48 ) .
