A pseudo sinus tachycardia originating from the right superior pulmonary vein. Successful ablation by a simplified, targeted ablation strategy.

We report the case of a young woman suffering from a permanent ectopic atrial tachycardia originating from the right superior pulmonary vein and mimicking a sinus tachycardia on the ECG. Using only 2 quadripolar catheters after a transseptal approach, the focus was successfully mapped to the posterior wall of the right superior pulmonary vein. The focus was successfully ablated during the same procedure using a 4-mm tip-irrigated catheter.
