title: A functional approach to the preexcitation syndromes.
abstract: Electrophysiologic studies have been used to elicit the mechanisms of the preexcitation syndromes and have become a therapeutic tool over the past decade. A thorough understanding of the physiology and anatomy of accessory pathways that are responsible for preexcitation and the associated arrhythmias is necessary before considering the various forms of intervention. The approach to patients with preexcitation syndromes is discussed, with an emphasis on the functional properties of accessory pathways and the associated arrhythmias.
