射频消融术后心房颤动患者的危险因素与护理

Risk Factors of Occurrence of Atrial Fibrillation After Flutter Ablation and Nursing Care

目的分析典型心房扑动(房扑)射频消融术后发生心房颤动(房颤)的危险因素及护理对策。方法对56例典型房扑行射频消融术的患者进行随访,分析发生房颤的危险因素。结果56例房扑患者全部消融成功,随访(14.0±12.2)个月,15例有房颤发作,其中3例进展为慢性房颤。术前有、无房颤病史者术后房颤发生率分别为7.5%、75.0%,后者显著高于前者(P<0.01)。房颤发作患者年龄(57.1±13.6)岁,无房颤发作患者(42.3±11.2)岁,两组比较,差异有显著性意义(P<0.05)。消融前有房颤发作病史是射频消融术后发生房颤的独立危险因素(P<0.05)。结论应对消融术前有房颤发作病史患者进行针对性护理,降低术后发生房颤的危险。

Objective To analyze the risk factors of occurrence of atrial fibrillation （AF） after flutter ablation and nur-sing measures. Methods Fifty-six patients with typical atrial flutter undergoing ablation were followed up and the risk factors of occurrence of AF were analyzed. Results All of the 56 patients with AF were successfully ablated. After a mean follow-up of （14.0±12.2） months, 15 patients experienced AF, 3 of whom progressed into chronic AF. The AF occurence rate of patients with AF history was 75.0%, which was significantly higher than that of the patients without AF history （7.5%,P〈0.01） . Patients with post-ablation AF were older （57.1±13.6 vs 42.3±11.2 years old, P〈0.05）. Cox proportional hazard analysis revealed that previous history of AF was the independent predictors of post-ablation AF（P〈0.05）. Conclusion Countermeasures should be adopted to the patients with history of AF before abla-tion for decreasing the risk of occurence of AF after flutter ablation.
