摘要
目的探讨胺碘酮在心房颤动复律及其后维持窦性心律的疗效与左心房内径(LA)大小之间的关系。方法89例慢性心房颤动患者,经超声心动图检测后,分为A组:41例,LA<40mm;B组:48例,LA≥40mm。观察2年,其主要终点为心房颤动复发。结果心房颤动的转复率,A组为100%,B组为77.08%(P<0.01);窦性心律维持率,A组为65.85%,B组为56.25%(P<0.01)。结论左心房内径的大小直接影响心房颤动复律的成功率,并能据此推测心房颤动复发的危险性大小,从而指导心房颤动的治疗。
Objective To study the therapeutic effect of amiodarone on diversion of atrial fibrillation （ AF ） and maintenance of sinus rhythm as well as the relationship between efficacy of amiodarone on diversion of atrial fibrillation and the diameter of left atrium （ LA ）. Methods 89 cases of chronic AF were divided into two groups after echocardiography ： group A （ n = 41, LA 〈 40 mm ） and group B （ n = 48 m, LA ≥ 40 mm ）. Two-year follow Up found that the primary end point was recurrence of atrial fibrillation. Results The diversion rate of atrial fibrillation was 100% in group A and 77.08% in group B （ P 〈 0.01 ）. The maintenance rate of sinus rhythm was 65.85% in group A and 56.25% in group B （ P 〈 0.01 ）. Conclusion The diameter of left atrium may influence the successful diversion of atrial fibrillation, which can be used to speculate on recurrence of atrial fibrillation, and direct the therapy of atrial fibrillation.
