Symptoms and Signs of Electrical Injuries

Doctor's Notes on Electrical Injuries

Electrical injuries are injuries to a portion of the body that has electricity pass through it; the electricity injury may include second and third degree burns of the skin, some extensive, some at the entry and exit site of the current and some small. However, internal damage is sometimes difficult to determine quickly, but may cause significant muscle damage and internal organ compromise. For example, irregular heartbeats or even heart beat stoppage can occur (CPR needs to begin and 911 needs to be called). Other symptoms include feeling weak, having hearing loss, be confused and/or disoriented. DC electrical sources tend to throw people away from the electrical shocking source while AC electrical sources tend to cause muscle spasms that prolong contact (for example, it can cause the hand to flex closed thereby gripping a touched AC wire).

The cause of electrical injuries is the electrical current that generates heat as it moves through body tissue and the current that overwhelms some or most of the body’s electrical system.
