ABSTRACT
Focal atrial tachycardia is defined as supraventricular tachycardia originating from discrete sites from which activation spreads to both atrial. In most clinical series, atrial tachycardia account for about 5% of all supraventricular arrythmias. This tachycardia can occur in children or adults within and without structural heart disease. Three potential mechanisms are described for its origin abnormal automaticity, triggered activity or microreentry. Catheter ablation has an important role in the management of focal atrial tachycardia and is now considered to be a first line therapy, can be improved with electroanatomical mapping system (CARTO) that allows reconstruction of the chamber geometry and allow visualization of the activation sequence; and can to improve the efficacy of catheter ablation.
