Abstract Objective： To explore the relationship between the level of NT-ProBNP before and after cardioversion treatment in patients with the recurrence of atrial fibrillation（ AF）. Method： 50 patients with AF were tested NTProBNP before and after admission. NT-ProBNP was compared between the successful cardioversion group and the failure group， coupled with that between the Maintenance of sinus rhythm group and the recurrence of atrial fibrillation group. Result： NT-ProBNP before and after treatment in failure group was significantly higher than the successful group （P<0.01）. NT-ProBNP after treatment in the recurrence of atrial fibrillation group was significantly higher than the maintenance of sinus rhythm group（ P<0.01）. Conclusion： The probability of successful cardioversion for those who had higher level of NT-ProBNP before and after cardioversion treatment is lower while controlling ventricular rate was desirable； it is easier to maintain sinus rhythm for those whose NT-ProBNP rapid returned to normal after treatment. The content of NT-ProBNP after treatment in patients with AF can act as the index to predict the recurrence of atrial fibrillation.
