Impacts of atrial fibrillation on sleep-disordered breathing: Insights from two heart failure cases.

ABSTRACT: Respiratory stability time (RST) has been proposed as an index for assessing heart failure-related sleep-disordered breathing. This case report examines the impact of catheter ablation for atrial fibrillation (AF) on RST and its relationship with heart failure. Two patients were analyzed: one with preserved ejection fraction (Case 1) and one with reduced ejection fraction (Case 2). In Case 1, RST improved significantly following ablation, accompanied by a decrease in plasma B-type natriuretic peptide levels. In contrast, while B-type natriuretic peptide levels decreased post-ablation in Case 2, RST showed minimal change, suggesting that the hemodynamic effects of restoring sinus rhythm had a lesser impact on respiratory stability. These findings indicate that the contribution of AF to the
