Atrial Tachycardia Catheter Ablation

Intracardiac electrophysiological examination and catheter ablation may be considered when recurrent atrial tachycardia with significant symptoms occurs, and drug control is poor or not tolerated. The decision usually integrates the type of arrhythmia (focal/reentrant), frequency of attacks and response to drugs, presence of structural heart disease, thrombosis and anticoagulation status, and whether there are suitable ablation and mapping conditions, and is ultimately evaluated by an electrophysiology specialist.
