Notes: regards ventricular fibrillation, this figure relates the effects current,
which flows the path left hand feet and for rising current. Increasing with
current magnitude and time, reversible disturbances formation
and conduction impulses the heart may occur
DC above Dangerous pathophysiological effects: severe burns, cardiac
disrhythmias, unconsciousness.
