Abstract

Background: Electrical injuries can be life-threatening, ranging from mild skin burns to serious organ damage. Low-voltage electric shocks (<1000V) are more common than high-voltage electric shocks. Phone chargers have been used quite frequently in recent years, especially at night, to charge portable phones. Cases of burns due to phone chargers have been reported.
Case Presentation: In this case report, a 30-year-old woman developed chest pain and symptomatic bradycardia after exposure to low-voltage electricity (5 V, 3 A) from the connector of a phone charger.
Conclusion: This case describes transient symptomatic sinus bradycardia temporally associated with contact with a mobile phone charger connector. However, causality cannot be established based on a single case. In symptomatic patients after such exposure, ECG assessment and short-term emergency department monitoring may be considered.
