WPW - Ventricular Preexcitation Syndrome

Premature ventricular excitation is due to the ventricle is prematurely excited by the impulse more rapidly travel through the muscular connection(s) between atrium(atria) and ventricle(s) outside the specialized conducting tissue, the accessory pathway(s)

Different pathways. Atrioventricular (Kent); Atriohisian; Nodoventricular; Fasciculoventricular. [illustration - available soon]

Pathway location and localization. [illustration - available soon]. A patient can have more than one pathway.

Characteristic [Case1], [Case2-1], [Case3]. [Case4] Other findings:

Clinical significance

Supraventricular tachycardia

Atrial fibrillation with antegrade conduction through accesory pathway. [ECG1]

Atrial flutter with antegrade conduction through accessory pathway. [ECG1]
