Objective To optimize antiarrhythmic drugs in the treatment of atrial fibrillation and atrial flutter patient different duration,improve the success rate and safety of cardioversion.Methods Make a retrospective analysis of 180 atrial flutter and 180 atrial fibrillation patients data,which were divided into group ibutilide,propafenone group and amiodarone group,Each group were further divided into duration ≤ 3d ＞ 3d,n =30,cardioversion rate was compared after 1.5h,and aralyzed by SPSS16.0.Results Atrial flutter cardioversion rate of ibutilide group ≤3d and 3d was 90％ and 83.33％ ;propafenone≤3d and 3d were 76.67％ and 36.67％,amineamiodarone were 73.33％ and 33.33％,cardioversion rate of three groups had no significant difference when atrial flutter duration ≤3d,P ＞ 0.05 ;Ibutilide cardioversion was significantly higher than propafenone,amiodarone when atrial flutter duration ＞ 3d,P ＜0.05 ;atrial fibrillation cardioversion rate of ibutilide group≤3d and 3d was 80％ and 73.33％ ;propafenone≤3d and 3d were 43.33％ and 26.67％,amineamiodarone were 50％ and 36.67％,Ibutilide cardioversion was significantly higher than propafenone,amiodarone when atrial flutter duration ≤3d,P ＜ 0.05; Ibutilide cardioversion was significantly higher than propafenone,amiodarone when atrial flutter duration ＞ 3d,P ＜0.05 ;the atrial flutter,atrial fibrillation total cardioversion rate of three groups were 81.67％,45.83％,48.33％,ibutilide was significantly higher than propafenone,amiodarone (P ＜ 0.05 ) ;the atrial fluttercardioversion of ibutilide was significantly higher than the atrial fibrillation rate( P ＜ 0.05 ).Conclusion For the duration of ≤ 3d patients,atrial flutter cardioversion rate of ibutilide.oropafenone,and amiodarone did not differ significantly,but the atrial fibrillation cardioversion rate of ibutilide was significantly higher;For the duration of＞ 3d patients,the atrial flutter and atrial fibrillation cardioversion rate of Ibutilide were higher than propafenone and amiodarone,when choose ibutilide,propafenone,or amiodarone for treating atrial flutter and atrial fibrillation according to individual arrhythmia.
