This 42y/o RHM was found 2/27/95 slumped over the steering wheel of the Fed Ex truck he was driving. He was cyanotic and pulseless according to witnesses. EMT evaluation revealed him to be in ventricular fibrillation and he was given epinephrine, lidocaine, bretylium and electrically defibrillated and intubated in the field. Upon arrival at a local ER his cardiac rhythm deteriorated and he required more than 9 counter shocks (defibrillation) at 360 joules per shock, epinephrine and lidocaine. This had no effect. He was then given intracardiac epinephrine and a subsequent electrical defibrillation placed him in atrial fibrillation. He was then taken emergently to cardiac catherization and was found to have normal coronary arteries. He was then admitted to an intensive care unit and required intraortic balloon pump pressure support via the right gorin. His blood pressure gradually improved and his balloon pump was discontinued on 5/5/95. Recovery was complicated by acute renal failure and liver failure. Initail CK=13,780, the CKMB fraction was normal at 0.8.
