A 49‐year‐old woman with dextrocardia and situs inversus underwent catheter ablation of paroxysmal atrial fibrillation (AF). During the electrophysiologic study, AF triggered by frequent premature atrial contractions (PACs) with a short coupling interval exhibiting a “P on T” pattern occurred. Pulmonary vein mapping revealed that those PACs originated from right‐sided (anatomic left) or left‐sided (anatomic right) pulmonary veins. In this case with mirror‐image dextrocardia, the P‐wave morphologies in leads I and aVL and the II/III ratio of the P‐wave amplitude were helpful for predicting a right‐ or left‐sided pulmonary vein origin.
