摘　　要：目的应用实时三平面组织多普勒技术评价阻塞性睡眠呼吸暂停综合征患者左心房整体功能。方法随机入组阻塞性睡眠呼吸暂停综合征患者26名,将患者分为合并高血压组(HT组)及不合并高血压组(NHT组),另收集健康志愿者10名(HC组),应用实时三平面组织多普勒技术计算左房整体收缩期峰值速度(SG)、舒张早期峰值速度(EG)、舒张晚期峰值速度(AG)和舒张早期与晚期峰值速度比(EG/AG)。结果 HT组较HC组EG(P<0.01)及AG(P<0.05)升高;HT组较HC组及NHT组EG/AG(P<0.01)降低。结论合并高血压的阻塞性睡眠呼吸暂停综合征患者舒张晚期左房收缩功能代偿性增强;EG/AG可作为评价OSAS患者心房功能的快捷指标。Objective To evaluate the left atrial global functions in patients with obstructive sleep apnea syndrome （OSAS ） by using real-time triplanetissue Doppler imaging . Methods 26 patients with o OSAS were randomly selected and divided into the non-hypertension group （Group NHT ） and the hypertension group （Group HT ） ,with 10 healthy controls recruited as the control group （Group HC） .Left atrial glob-al peak systolic velocity （SG） ,peak early diastolic velocity （EG） and peak late diastolic velocity （AG） were measured by by using real-time triplanetissue Doppler imaging .Results EG and AG was both increased sig-nificantly in Group HT when compared with that in Group HC （ P〈0 .01 ;P〈0 .05） .EG/AG was re-duced significantly in Group HT when compared with that in Group HC and Group NHT （ P〈 0 .01） . Conclusion Real-time triplane method is feasible for the evaluation of left atrial functions in patients with OSAS ,and EG/AG can be used as a convenient index .
