Catheter ablation guided by ECG and mapping techniques is highlighted as a highly successful primary treatment strategy for symptomatic focal atrial tachycardia.
Supports ablation for symptomatic focal AT; extends observational data but leaves open need for randomized confirmation.
Focal atrial tachycardia (AT) is a relatively uncommon cause of supraventricular tachycardia, but when present is frequently difficult to treat medically. Atrial tachycardias tend to originate from anatomically determined atrial sites. The P-wave morphology on surface electrocardiogram (ECG) together with more sophisticated contemporary mapping techniques facilitates precise localisation and ablation of these ectopic foci. Catheter ablation of focal AT is associated with high long-term success and may be viewed as a primary treatment strategy in symptomatic patients.
