The diagnosis of Wolff-Parkinson-White (WPW) syndrome is typically made with formal electrocardiographic (ECG) monitoring in conjunction with clues from the history and physical examination. Evaluate patients presenting with symptomatic tachycardia (supraventricular tachycardia [SVT] or wide-complex tachycardia) for the presence of preexcitation on the 12-lead ECG results, and consider consultation with a cardiac electrophysiologist. Noninvasive mapping of cardiac arrhythmias is also possible with a 252-lead ECG and computed tomography (CT)-based three-dimensional (3D) electroimaging. [25]
