Explanation lettering: C = shown as A · E = shown as B · B = shown as C · A = shown as E

The 2023 AF guideline emphasizes early rhythm control in AF with HFrEF/tachycardia-induced cardiomyopathy, including catheter ablation to improve EF. Rate control only (B) may not reverse cardiomyopathy; AV node ablation (C) is not first-line; aspirin (D) is irrelevant; stopping beta-blocker (E) is harmful.
