Cardiac dysrhythmias
Respiratory arrest
Seizures
Fatalities due to asystole or V-fib usually occur prior to arrival
Most common dysrhythmia at presentation is A-fib (V-fib is more common, but patients are dead PTA)
Asymptomatic patients with normal ECGs do not develop later dysrhythmias after <1000V<unk> 
For uncomplicated<unk>  if normal EKG then routine ECG monitoring and cardiac biomarkers unnecessary.

Contraction band necrosis
Medial necrosis of large vessels
Aneurysm formation
Coagulation necrosis of small vessels
Can lead to compartment syndrome
Aneurysm formation
Can lead to compartment syndrome
Occurs in 50% of patients with high-voltage<unk> 
Brain injury ranges from transient LOC to CVA to respiratory arrest
High voltage<unk>  involving head are frequently associated with coma and persistent vegetative state
Forceful muscle contractions can cause fracture and joint dislocations (especially shoulder)
May occur with voltages as low as 120V
Compartment Syndrome
Usually associated with high-voltage<unk> 
May occur even with 120V shocks if contact is sustained for longer than few seconds
Patient experiences ongoing muscle pain with movement
Need for fasciotomy predicted by:
Myoglobinuria
Burns >20% BSA
Full-thickness burn >12% BSA
Rhabdomyolysis
Associated with:
Contact with >1000V
Prehospital cardiac arrest
Crush injury
Compartment syndrome
Full-thickness skin burns

Cataract formation has been described weeks to years after<unk>  injury

May be damaged by current or hemorrhage
Check hearing in all patients
Often seen at<unk>  contact areas
Seriously injured patients often have burns on either arm or skull + feet
Most patients with burns from<unk>  injury require admission and care by burn specialist
Lichtenberg figures (not true burns) are pathognomonic for lightning strike
Seriously injured patients often have burns on either arm or skull + feet
Suspect in patients with:<unk>  burns of abdominal wall
History of a fall, nearby explosion, or other mechanical trauma<unk>  burns of abdominal wall
History of a fall, nearby explosion, or other mechanical trauma
In general, evaluate as for the adult, looking for multi-system involvement
Perform an ECG in all patients, regardless of voltage
An oral commissure burn (from chewing on power cord) will create significant edema and necrosis
The child may need Plastic Surgery or Head and Neck Surgery consultation to avoid microstomia
1-2 weeks after the burn, the eschar may fall off, exposing the labial artery and causing significant hemorrhage
Provide clear and thorough precautionary advice including first aid for bleeding (pinch buccal mucosa against outside of cheek until arrival to hospital)
