to determine the effect of strong analgesics on electrical instability ( vulnerability to ventricular fibrillation ) , we examined the action of fentanyl ( 60 micrograms/kg ) , sufentanil ( 10 micrograms/kg ) and carfentanil ( 3 micrograms/kg ) on the ventricular fibrillation threshold ( vft ) in a dog model of coronary artery occlusion .
