Electrocution induced symptomatic bradycardia necessitating pacemaker implantation.

Area of Science:

• Cardiology
• Neurology
• Occupational Health

Background:

• Electrocution is a common workplace injury, typically causing arrhythmias or sudden death.
• Permanent sinus bradycardia after electrocution is a rare but debilitating outcome.

Observation:

• A young patient experienced non-fatal electrocution.
• The injury resulted in persistent low heart rate (sinus bradycardia).
• This condition significantly impacted the patient's lifestyle.

Findings:

• The patient developed sinus node and autonomic dysfunction with vagal predominance.
• Successful treatment was achieved using a dual-chamber, rate-responsive pacemaker.

Implications:

• This case highlights a rare complication of electrocution.
• Pacemaker implantation can effectively manage electrocution-induced sinus bradycardia.
• Understanding these mechanisms aids in managing electrical injury patients.
