Abstract
The efficacy of electrical countershock, cardiac massage, epinephrine and procaine in stopping ventricular fibrillation and restoring a competent ventricular contraction was studied in anesthetized dogs. It was found that countershock is a reliable means of stopping fibrillation. However, it must be preceded by cardiac massage if not applied promptly after the initiation of fibrillation. Epinephrine helps restore a competent ventricular contraction once fibrillation has been stopped by countershock but it increases the incidence of recurrence of fibrillation. The doses of procaine which constitute a reliable means of stopping fibrillation depress the rhythmicity of the heart to such an extent that the cessation of fibrillation is followed by prolonged periods of cardiac standstill.
