The efficacy and safety of a nurse-led electrical cardioversion service for atrial fibrillation over a 2-year time period

Aims Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide, with a significant impact on morbidity, mortality, and utilization of healthcare resources. Electrical direct-current cardioversion (DCCV) is offered to patients with ongoing symptoms despite medical management. In this study, we aim to evaluate the safety and efficacy of a specialized nurse-led DCCV service. Methods and results This was a retrospective cohort study analysing the outcome of patients presenting with AF or flutter, who were subsequently referred for a nurse-led DCCV procedure between August 2017 and December 2019. Analysis included a total of 341 patients (mean age = 68.37; standard deviation = 10.96) who presented with either AF (N = 267; 78.30%) or atrial flutter (N = 74; 21.70%). Approximately 30% of patients were females (N = 101) and 70% were males (N = 240). Of the 341 patients who underwent DCCV, 299 were successfully cardioverted (87.68%). Of those patients successfully cardioverted, 167 remained in sinus rhythm after 6 weeks (55.85%); 93 patients reverted back to AF (31.10%). Thirty-eight patients were lost to follow up (12.71%). Of all 341 patients who underwent DCCV, only 24 patients were admitted to hospital during the subsequent 3-month period (7.04%). Importantly, no patients were admitted as a direct complication of the DCCV procedure. Conclusion Overall, data gathered from this study provides positive evidence to support the use of a nurse-led DCCV service. In addition to obtaining very successful cardioversion rates, we found low remission rates, with a very low hospital readmission rate for AF-related issues after successful DCCV.
