Electrocardiogram

Although polymorphic ventricular tachycardia is a common arrhythmia in patients with Anderson syndrome, decompensation into a hemodynamically compromising rhythm, or ventricular fibrillation, is rare. The following EKG findings are seen in patients with Andersen-Tawil syndrome:

  • Biphasic U waves in limb leads
  • Widened T-U junction
  • Large U waves
  • Prolonged terminal T wave downslope
  • Prolonged Q-U intervals
  • Premature ventricular contractions
  • Polymorphic ventricular tachycardia
  • Bidirectional ventricular tachycardia
