Junctional ectopic tachycardia is recognized predominantly as a postoperative arrhythmia after surgery for congenital heart disease.

We present a case of junctional ectopic tachycardia that occurred in the setting of abdominal trauma caused by child abuse and then explore the significance of this arrhythmia in a patient with trauma.
