Abstract
The paper describes a series of animal experiments in which large-surface-area disk electrodes were used to study the current density required for ventricular fibrillation. The electrical currents were introduced to the heart both by applying the electrodes directly to the heart and by applying the electrodes to the surface of the chest near the heart. The electrode areas studied ranged from 1000 to 30 000 mm2. The results show that, for large-area electrodes, fibrillation thresholds are determined by current density. The thresholds approach a constant value of 3·5 μA mm−2
