Electrocardiographic manifestations following electric injury

A 23-year-old man admitted with electric injury had intermittent episodes of non-sustained ventricular tachycardia, recurrent ventricular premature complexes, atrial fibrillation, supraventricular tachycardia and ST changes suggestive of pericarditis. The non-sustained ventricular tachycardia and ventricular premature complexes responded to intravenous lidocaine, atrial fibrillation and supraventricular tachycardia to intravenous digoxin.
