Implication

May aid pre-procedural localization of focal left atrial tachycardias; leaves open prospective validation of P-wave algorithms.

Population

140 patients with atrial tachycardia undergoing successful ablation (143 AT foci), mean age 44.6+/-17.9 years, 56 men.

Intervention

Electrophysiological mapping and ablation

Outcome

Topographic distribution of focal left atrial tachycardias and associated P-wave morphology and cycle length

Focal left atrial tachycardias most commonly originate near the pulmonary veins or mitral annulus, and can be differentiated by specific P-wave morphologies such as positive P waves in V1 for PV origins.
