【摘要】：目的探讨实时三维超声心动图(RT-3DE)评估阵发性房颤患者左心房功能的研究。方法 45例阵发性房颤患者为病例组,43例正常人为对照组。所有患者行常规超声心动图检查,获取左房径线、二尖瓣血流频谱E波和A波速度、E波与A波的速度比值(E/A),应用组织多普勒获得二尖瓣瓣环室间隔侧、侧壁侧瓣环舒张早期速度峰值(Ve)、舒张晚期速度峰值(Va)。应用实时三维超声心动图采集动态图像,脱机分析计算左房最大容积(LAVmax)、左房最小容积(LAVmin)、左房收缩期前容积(LAVpre A)、左房储蓄容积(ARV)、左房主动排空容积(AEV)。结果与正常对照组比较,阵发性房颤组的LA径线、VE、E/e、LAVmax、LAVpre A和LAVmin显著增大,而ARV/LAVmax、AEV/LAVpre A明显减少,差异有统计学意义(P0.05)。结论实时三维超声心动图检测证实阵发性房颤患者的左房的储备功能及辅助泵功能有明显障碍。
[Abstract]:Objective to investigate the real-time three-dimensional echocardiography (RT-3DE) assessment of left atrial function in patients with paroxysmal atrial fibrillation. Methods 45 patients with paroxysmal atrial fibrillation patients and 43 cases of normal control group. All patients underwent routine echocardiography, left atrial diameter gets, mitral valve blood flow spectrum of E wave and A wave velocity, E wave and A wave velocity ratio (E/A), obtained by tissue Doppler mitral annulus of interventricular septum, lateral wall of the lateral mitral annulus early diastolic peak velocity (Ve), late diastolic peak velocity (Va). The application of real-time three-dimensional echocardiography in dynamic image acquisition, offline analysis of left atrial volume (LAVmax), minimum left atrial volume (LAVmin), left atrial systolic volume (LAVpre A), the left atrial volume savings (ARV), left atrial emptying volume (AEV). Results compared with normal control group, paroxysmal AF group LA diameter VE, E/e, LAVmax, LAVpre, A and LAVmin a significant increase ARV/LAVmax, AEV/LAVpre, A decreased significantly, the difference was statistically significant (P0.05). Conclusion by real-time three-dimensional echocardiography reserve and auxiliary pump function detected by left atrial paroxysmal atrial fibrillation in patients with significant obstacles.

【正文快照】： 心房颤动(atrial fibrillation,AF)是临床最常见的心律失常之一。房颤可造成心房的血流动力学异常,从而进一步影响整个心脏的功能[1]。准确评价房颤患者的左房功能的变化对临床治疗及预后评价具有重要的指导作用。实时三维超声心动图是新近发展起来并开始应用于临床心脏疾病的
