Definition 1

A cardiac conduction disorder characterized by an electrocardiographic finding of ventricular pre-excitation, which is a short PR interval and a long QRS interval with a delta wave. Most individuals are asymptomatic; however they can experience periods of palpitations, shortness of breath or syncope during tachycardic episodes. (NCI Thesaurus)

Definition 2

A disorder characterized by the presence of an accessory conductive pathway between the atria and the ventricles that causes premature ventricular activation. (NCI Thesaurus/CTCAE)

Definition 3

A form of pre-excitation characterized by a short PR interval and a long QRS interval with a delta wave. (NLM, Medical Subject Headings)

Definition 4
