Methodology of Typical Accessory Pathway Catheter Ablation

Abstract

Accessory pathways are abnormal electrical conductions between the atrial and ventricular myocardium, bypassing the atrioventricular node and as such are an important substrate for arrhythmias. Ablation is a curative treatment and should always be offered to symptomatic patients and asymptomatic patients with high risk professions. Adequate knowledge and understanding of different mapping and ablation techniques is pivotal to achieve successful outcomes.
