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
