Cardioversion of atrial fibrillation and flutter: Trends, outcomes, and rhythm management strategies over 2 decades
Authors' conclusion
DCCV case volume has increased markedly, and subsequent catheter ablation is increasingly common. Findings highlight a growing preference for rhythm control and emphasize the importance of scaling access to DCCV.
