Incessant monomorphic ventricular tachycardia during febrile illness in a patient with Brugada syndrome: fatal electrical storm.

A 55-year-old male with structurally normal heart presented with sustained monomorphic ventricular tachycardia (VT) and was cardioverted into sinus rhythm revealing a right bundle branch block pattern at baseline electrocardiography. Sustained monomorphic and nonsustained polymorphic VT were reproducibly inducible during electrophysiological study. During the diagnostic workup, the patient experienced fever due to hospital based pneumonia, which unmasked typical ST segment changes of Brugada syndrome. In the intensive care unit, fever became intractable leading to incessant monomorphic VT, which was resistant to all medical manoeuvers resulting in the patient's death.
