title: Macro-reentrant atrial tachycardias.
abstract: Macro-reentrant atrial arrhythmias development is conditioned by the presence of fixed (anatomical or acquired) or functional barriers of conduction with areas of slow conduction at critical atrial sites. It may occur with or without underlying heart disease. Recent development of sophisticated 3D mapping systems has greatly contributed to a better understanding of these atrial arrhythmias. However, classical electrophysiological manoeuvres are usually efficient to locate the tachycardia circuit and to find critical isthmuses as well. In the vast majority of the cases, these techniques allow physicians to cure these tachycardias with a high success rate using catheter ablation.
