Catuama was tested on the reversion and prevention of ventricular fibrillation (VF) in the isolated rabbit heart. Catuama was perfused in the isolated perfused rabbit heart. Its effects on intraventricular conduction, heart rate, and monophasic action potential (MAP) duration were evaluated, and sustained ventricular fibrillation was induced. The effects on reversion and reinduction of arrhythmia were observed, and new measures were taken in the hearts that reverted. Catuama and T catigua reverted ventricular fibrillation in all hearts, prevented reinduction, and prolonged intraventricular conduction. Catuama prolonged MAP phase 2. On the other hand, P cupana reverted ventricular fibrillation in 3 of 5 hearts, but depressed automatism, prolonged MAP phase 3, and did not prevent reinduction.  Catuama reverted and prevented ventricular fibrillation in this model. T catigua extract is probably the main agent responsible for the beneficial actions observed.
