Intra‐Atrial Conduction Block . A 42‐year‐old woman with a history of cardiomyopathy and multiple ablation procedures for atrial tachycardia developed intra‐atrial conduction block that mimicked atrioventricular (AV) nodal block during radiofrequency ablation at the cavotricuspid isthmus. She was treated with atrial pacing (from the coronary sinus), which overcame intra‐atrial conduction block and resulted in AV nodal conduction.
