Abstract

A 13-year-old boy had a positive P wave in V1 with a negative P wave in lead I, aVL, and aVR, as well as a positive P wave in the inferior leads, which correlated with a left atrial appendage (LAA) atrial tachycardia (AT) focus. P-wave morphologies can provide clues regarding an AT's origin, and this P-wave negative in lead I favored LAA AT. Careful mapping along the atria and coronary sinus to determine the earliest site of activation for the surface P wave is a reliable method for precisely localizing the AT origin as a target for catheter ablation.

Keywords: Atrial tachycardia; Catheter ablation; Left atrial appendage.
