经皮二尖瓣球囊扩张成形术后心房颤动电复律的分析

Analysis on Cardioversion of atrial fibrillation following percutaneous balloon mitral valvuloplasty

对经皮二尖瓣球囊扩张成形术后心房颤动同步直流电复律４５例的复律过程进行观察和随访，探讨复律的影响因素及窦性心律的维持情况。结果表明，复律失败及复律后出现的心律失常组的年龄、房颤持续时间、心瓣膜病程、左房内径等均高于复律成功且无心律失常组（Ｐ＜０．０５）。进一步分析发现，复律成功与放电能量、房颤持续时间、转复前心率、左房内径等因素有关。复律时机的选择对窦性心律的维持有一定关系。

The effect of cardioversion of atrial fibrillation following percutaneous balloon mitral valvuloplasty was observed in 45 patients with rheumatic heart disease for investigating the factors in cardioversion and condition of sinus rhythmic maintenanceThe results showed the age of patient,the duration of artial fibrillation,duration of valvulopathy and calibre of left artium were all higher or longer in the group with failure cardioversion and arrhythmia than those in the group with succeful cardioversion and no arrhythmia (P<005)After certain steps of investigation,it was discovered the success of cardioversion depends on electric power,atrial fibrillation duration,the cardiac frequency before cardioversion and calibre of left atrium,relativelyIt was discovered the right choice of cardioversion chance was related to sinus rhythmic durationAuthor suggests that the administration of quinidie should be quite effective in the maintenance of sinus rhythm after cardioversion
