NPPB and Paroxysmal atrial fibrillation: Similarly, the BNP value was higher in the paroxysmal AF than in the sinus rhythm group (116 (70–238) mg/dL versus 34 (14–72) mg/dL, p < 0.05) and further increased in the chronic AF group (269 (199–423) p < 0.05 versus paroxysmal AF and sinus rhythm groups).
