Using Flecainide to Treat Atrial Fibrillation

Can Global Peak Longitudinal Strain Measurements in Combination With Non-invasive ECG Parameters Predict the Success or Failure of Flecainide Treatment for Atrial Fibrillation Patients?

Observational Lund University · NCT05084495

This study is testing if the heart medication flecainide can safely help people with atrial fibrillation maintain a normal heart rhythm over a year.

What this trial studies

This prospective observational study aims to evaluate the effectiveness and safety of flecainide in patients with atrial fibrillation who are eligible for this treatment. Participants will be monitored over a 12-month period with four clinical visits, during which clinical data, advanced echocardiographic data, and ECGs will be collected. The study will analyze outcomes such as maintaining normal sinus rhythm, the number of AF-free months, successful electrical cardioversion, side effects, and mortality. The goal is to improve the use of flecainide by addressing the current 'trial and error' approach in its administration.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with atrial fibrillation who are eligible for flecainide treatment.

Not a fit: Patients with atrial fibrillation who are not eligible for flecainide treatment or those under 18 years old may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective and safer use of flecainide for patients with atrial fibrillation.

How similar studies have performed: While the use of flecainide in atrial fibrillation has been explored, this specific observational approach focusing on detailed echocardiographic analysis is relatively novel.
