BACKGROUND: An understanding of normal atrial activation during sinus rhythm can inform catheter ablation strategies to avoid deleterious impacts of ablation lesions on atrial conduction and mechanics. OBJECTIVE: The purpose of this study was to describe how the sinus node impulse originates, propagates, and collides in right and left atria with normal voltage. METHODS: Fifty consecutive patients undergoing catheter ablation of atrial fibrillation with endocardial atrial voltage >0...
