心房颤动f波形态对伊布利特转复心房颤动成功率的影响

目的探讨心房颤动f波形态的不同对伊布利特转复心房颤动有效率的影响。方法抽取56例心房颤动患者,根据应用伊布利特后是否转复成功分为转复成功组和转复不成功组,分别测定两组f波振幅及时限的平均值进行分析,比较两组差异是否有统计学意义。结果应用伊布利特转复56例心房颤动患者,转复成功组38例,转复不成功组18例,其中转复成功组f波振幅(0.54±0.46)mv,转复不成功组f波振幅(0.70±0.61)mv,两组比较差异无统计学意义(P>0.05);转复成功组心房颤动f波时限为(96.00±40.00)ms,转复不成功组心房颤动f波时限为(68.00±42.00)ms,两组比较差异有统计学意义(P<0.05)。结论心房颤动f波振幅大小对伊布利特转复心房颤动成功率无影响,房颤f波时限大小对伊布利特转复心房颤动成功率有影响。

The Impact of the Form of F Waves on Effective Rate of Converting Atrial Fibrillation With Ibutilide

Objective To study the influence of f-wave form in converting atrial fibrillation(AF) with Ibutilide.Methods 56 AF patients,according to the effectiveness of Ibutilide for conversion,were categorized into conversed group and unconversed group.Both were measured for the mean value of amplitude and duration of F waves and underwent a statistical analysis.Results Among the 56 AF cases,38 recovered successfully with ibutilide,and 18 failed.The mean value of amplitude in conversed group and unconversed group were 0.54±0.46mv and 0.70±0.61mv respectively,which showed no significant statistical difference.The mean value of duration of f waves in conversed group and unconversed group were 96ms±40ms and 68ms±42ms,in which there was significant statistical difference between them.Conclusions The duration of f waves do have effect on the effective rate of converting AF with Ibutilide and the amplitude of f waves do not.
