P-wave morphology in focal atrial tachycardia using a 3D numerical model of the heart

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.

The Difference ◽

The Right

Focal atrial tachycardia is an atrial arrhythmia arising in either the left or the right atrium, usually faster than 100 min−1 and regular, with a P-wave morphology that is different from the normal P-wave morphology associated with sinus rhythm—the difference in morphology being more pronounced the further away the focus lies from the sinus node. The ventricular rate is generally fast also, dependent on the nature of the atrioventricular conduction (AV); 1:1 conduction may be seen, especially in younger patients or patients with accessory pathways capable of very rapid antegrade conduction; alternatively, 2:1, Wenckebach-type, or higher-grade AV block may be seen.
