作者对126例房颤病人进行超声心动图检查,旨在探讨房颤与左房大小的关系。126例房颤病人测值经统计学处理,各组均以1978年大连召开的超声诊断学术会议上通过的正常统一标准(下称正常值)。(1)风心病人阵发性房颤时左房内径41.5±3.90,持续性房颤时左心房53.0±11.6,以正常值为对照,左房内径均显著大于正常人(P<0.01)。(2)冠心病阵发性房颤者左心房内径35.3±9.3,持续性房颤者左房内径43.2±10.4,均显著大于正常人(P<0.01),(3)但冠心病持续性房颤病人与风心病人相比,左房内径显著小于后者,两者相差非常显著(P<0.01),冠心病阵发性房颤左房内径也小于风心病,两者相差显著(P< 0.05),(4)甲状腺功能亢进病人发生房颤时左房内径与正常人相比无显著差异(P>0.05),(5)特发性房颤病人左房内径与正常人相比也无显著差异(P>0.05),(6)扩张型心肌病房颤时左
The author of 126 patients with atrial fibrillation echocardiography, to explore the relationship between atrial fibrillation and left atrial size. 126 cases of atrial fibrillation patients measured by statistical analysis, each group are based on the standard of ultrasound diagnosis conference held in Dalian in 1978 to adopt the normal uniform standards (hereinafter referred to as normal). (1) In patients with rheumatic heart disease, the left atrial diameter was 41.5 ± 3.90 in patients with paroxysmal atrial fibrillation and the left atrium was 53.0 ± 11.6 in patients with persistent atrial fibrillation. The left atrial diameter was significantly larger than that in normal subjects (P <0.01). (2) The diameter of the left atrium of patients with CHD was 35.3 ± 9.3 and the average diameter of left atrium was 43.2 ± 10.4 in patients with CHD (all P <0.01). (3) Compared with patients with rheumatic heart disease, patients with thoracic atrophy had a significantly smaller diameter of left atrium than those with rheumatic heart disease (P <0.01). The left atrial diameter of patients with paroxysmal atrial fibrillation was also lower than those with rheumatic heart disease (P < 0.05). (4) There was no significant difference in the left atrial diameter between normal hypertensive patients and hyperthyroid patients (P> 0.05). (5) The left atrial diameter of patients with idiopathic atrial fibrillation was also lower than that of normal subjects Significant difference (P> 0.05), (6) dilated cardiomyopathy left atrial fibrillation
