房颤自行复律可能性的初步探讨

目的　初步探讨房颤自行复律的可能性和相关因素。方法　回顾性分析 173例房颤发作持续至入院小于 72小时患者的临床和心脏扇超资料 ,并作自行复律和非自行复律组的比较。结果　 173例患者中 6 5 .32 %房颤自行复律 ,自行复律组和非自行复律组相比 ,房颤发作持续至入院小于 2 4小时者多见(P <0 .0 1) ,入院时心功能较好 (P <0 .0 1) ,EF较大 (P <0 .0 1) ,左房较小 (P <0 .0 5 )。结论　房颤发作持续至入院小于 72小时患者中约 6 5 %可自行复律。自行复律者多为房颤持续发作 2 4小时内入院 ,入院时心功能较好 ,左房较小。

Likelihood of spontaneous conversion of atrial fibrillation to sinus rhythm

Objective To preliminarily explore the likelihood and associated factors of spontaneous conversion (SC) of atrial fibrillation (AF) to sinus rhythm. Methods Analysed retrospectively clinical and echocardiographic datas of 173 patients with AF duration less than 72h from onset to admission, compared SC group with non-SC group. Results The rate of conversion to sinus rhythm spontaneously was 65.32%, compared with non-SC, there were more patients with AF duration less than 24h from onset to admission in SC group, which also had better heart function, EF and smaller left atrium. Conclusion About 65% of patients with AF duration from onset to admission less than 72h could converte to sinus rhythm spontaneously. Patients with SC arrived at hospital often within 24h, and had better heart function and smaller left atrium.
