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。
Objective To investigate the effect of different f-wave morphologies of atrial fibrillation on the efficiency of a-fibrillation in patients undergoing iburatt. Methods Fifty-six patients with atrial fibrillation were divided into two groups according to the success of the application of ibutilide. The patients were divided into two groups: the successful group and the unsuccessful group. The average amplitude and time of the two groups were analyzed. The difference is statistically significant. Results In 56 patients with atrial fibrillation who were treated with ibutilide, 38 patients in the successful group and 18 patients in the unsuccessful group were transfered. The amplitude of f wave in the successful group was (0.54 ± 0.46) mv, f Wave amplitude (0.70 ± 0.61) mv, there was no significant difference between the two groups (P> 0.05). The f-wave time of atrial fibrillation in successful group was (96.00 ± 40.00) ms, (68.00 ± 42.00) ms, the difference between the two groups was statistically significant (P <0.05). Conclusion The magnitude of f-wave amplitude of atrial fibrillation has no effect on the success rate of a-fibrillation of ibutilide. The f-wave duration of atrial fibrillation has an impact on the success rate of a-fibrillation.
