Study design details

• Main study objective:
  To evaluate the effectiveness and safety of vernakalant for the rhythm control of AF in the context of clinical practice, in comparison with its treatment alternatives.
• Outcomes:
  Percentage of patients with reversion to sinus rhythm in the first hour after treatment, - Percentage of patients with reversion to sinus rhythm in the first 12 hours/24 hours. - Percentage of patients requiring hospitalization. - Hospital stay - Percentage of patients with AF recurrence in the first 5 days/ 30 days/ 6 months
• Data analysis plan:
  The incidence in exposed (cohort treated with vernakalan and in non-exposed (treated with other cardioversión drug) will be calculated for each of the effectiveness variables. From these, the measures of association relative risk (RR), absolute risk reduction (RAR) and relative risk reduction (RRR) will be calculated for each of the variables, with their 95% CIs. The RR adjusted for comorbidities and prognostic factors will be estimated.
