Overview

There are no ECG findings associated with [disease name].

OR

An ECG may be helpful in the diagnosis of [disease name]. Findings on an ECG suggestive of/diagnostic of [disease name] include [finding 1], [finding 2], and [finding 3].

Electrocardiogram

There are no ECG findings associated with [disease name].

OR

An ECG may be helpful in the diagnosis of [disease name]. Findings on an ECG suggestive of/diagnostic of [disease name] include

• [Finding 1]
• [Finding 2]
• [Finding 3]

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
