Cardioversion of atrial fibrillation and flutter: Trends, outcomes, and rhythm management strategies over 2 decades

Heart RhythmPublished

  • multi-institutional experience of direct current cardioversion (DCCV) over 2 decades
  • case-level analyses
  • patient-level analyses

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.
