I am asked to draw a picture of a person 1 second before patient is defibrillated and 10 seconds after a patient is defibrillated. I am asked to draw a general picutre of the electric field lines and charges at these two points. I know that the goal of defibrillation is to enterfere with the reentry of circuits to bring the electric activity to a stop of to eliminate fibrillation. Does this mean that the amount of electric field lines after defibrillation is less than the amount of electrical activity before? This question is somewhat confusing for me so any help or explanation would be appreciated!
