The current of injury from the damaged area is the most likely factor to increase the tendency of the heart to fibrillate after an ischemia-induced myocardial infarction. The damaged area of the heart creates an area of depolarization that can act as a source for abnormal electrical signals and reentry circuits, which can lead to ventricular fibrillation.
