Overview

An ECG may be very helpful in the diagnosis of Andersen-Tawil Syndrome. Findings on an ECG diagnostic of Andersen-Tawil Syndrome include a long QTc (LQT) interval, U waves, wide T-U junction and T-waves.

Electrocardiogram

An ECG may be helpful in the diagnosis of Andersen-Tawil Syndrome. Findings on an ECG diagnostic of Andersen-Tawil Syndrome include:[1]

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
