目的探讨左心房改变与心房颤动发生的关系。方法根据心电图和动态心电图的检测,将160例患者分为三组,持续性房颤患者54例为A组,阵发性房颤患者52例为B组,仅有心电图P波增宽的患者54例为C组。所有入选患者均经超声心动图检测左心房内径,观察患者窦性心律时心电图P波最大时限(Pmax)和P波离散度(Pdisp),并分析与房颤发生的关系。结果患者心电图P波切迹明显,Pmax增宽,Pdisp大者房颤发生率高;超声心动图检测左房内径大者房颤发生率高,持续性房颤比阵发性房颤患者左房内径更大(P<0.01)。结论左心房扩大、Pmax增宽、Pdisp增大与房颤的发生以及持续的时间有密切关系。
Objective To investigate the relationship between left atrial appendage and the occurrence of atrial fibrillation. Methods According to the detection of electrocardiogram and ambulatory electrocardiogram, 160 patients were divided into three groups: 54 patients with persistent atrial fibrillation were in group A, 52 patients with paroxysmal atrial fibrillation were in group B, and only patients with P wave broadening 54 cases for the C group. All selected patients were examined by echocardiography of the left atrium diameter, ECG observed in patients with sinus rhythm Pmax and P wave dispersion (Pdisp), and analysis of the relationship with the occurrence of atrial fibrillation. Results The electrocardiographic P wave notch was significant, the Pmax was widened, and the incidence of atrial fibrillation was high in patients with large Pdisp. The echocardiography was used to detect the high incidence of atrial fibrillation in patients with a large left atrium and persistent atrial fibrillation compared with those in patients with paroxysmal atrial fibrillation Larger (P <0.01). Conclusions Left atrium enlargement, Pmax broadening, Pdisp increasing are closely related to the occurrence and duration of atrial fibrillation.
