ABSTRACT
Diagnosis and management of complex heart rhythm disor-
ders, in particular atrial fibrillation (AF), continues to evolve.
Understanding of the mechanisms of arrhythmias, along
with advances in catheter ablative technology and advanced
mapping techniques, facilitates execution of electrophysio-
logic procedures which, in experienced centers, can be car-
ried out with high efficacy and low complication rates.
