Abstract:
We present a case of a young boy who developed persistent tachycardia despite fluid resuscitation, antipyretics, and analgesia after a Fontan procedure. Review of telemetry and ECGs revealed repolarization abnormalities, including the appearance of T-wave alternans, for which an uncommon cause was ultimately identified.
