Nonsustained ventricular tachycardia resolving under general anesthesia: a case presentation.

A 14-year-old competitive gymnast presented for a left distal femur epiphysiodesis. She had previously sustained a right femur fracture and was noted to have asymptomatic NSVT perioperatively, which improved while under general anesthesia (GA). Holter monitor showed NSR with uniform ventricular ectopy occurring 30% of the time, including during sleep. Echocardiography was normal and exercise testing was negative. While under GA with isoflurane, her NSVT terminated and resumed on emergence. She returned eleven months later for a right distal femoral osteotomy. Her baseline NSVT again improved after induction, and returned five minutes after emergence.
