The type and severity of electrical injury are dependent on the voltage, type and strength of current, resistance to flow, duration of contact and pathway of electrical current.
Alternating current (AC) is more dangerous than direct current (DC) at the same voltage, because of the risk of muscle tetany and prolonged contact.
Patients who sustain low voltage electrocution and are asymptomatic with a normal physical exam and electrocardiography (ECG) can be safely discharged from the emergency department (ED) without ancillary testing.
