Atrial Fibrillation Data


Atrial Fibrillation (AF) data is obtained from a randomized trial to study the effect of surgical ablation as a treatment option for AF among patients with persistent and long-standing persistent AF who requires mitral valve surgery. Patients were randomized into two groups: mitral valve surgery with ablation and mitral valve surgery without ablation. Patients in the ablation group were further randomized into two types of procedure: pulmonary vain isolation (PVI) and biatrial maze procedure. These patients were followed weekly for a period of 12 months. The primary outcome of the study is the presence/absence of AF (binary longitudinal response). Data includes 228 patients. From 228 patients, 7949 AF measurements are available with average of 35 measurements per patient.
