阵发性心房颤动患者左房内径变化的分析

An Analysis on the Change of Dimensions of the Left Atria in the Patients with Paroxysmal Atrial Fibrillation

目的:检测阵发性心房颤动(PAF)患者的左房内径(LAd)的变化,探讨LAd与PAF的关系。方法:PAF组34例包括特发性心房颤动18例(Ⅰ组)、伴有高血压和(或)冠心病者16例(Ⅱ组),健康对照组36例;测定LAd,分析LAd与PAF的关系。结果:PAFⅠ组LAd为(28.69±5.35)mm,与对照组的(28.08±5.93)mm相比较差异无显著性(P>0.05);PAFⅡ组LAd为(38.29±5.89)mm,与对照组的(28.08±5.93)mm相比较差异有显著性(P<0.05)。结论:特发性房颤的LAd不增大,PAF伴有高血压和(或)冠心病的患者LAd增大。

Objective: To observe the change of the left atrial dimension (LAd) in the patients with paroxysmal atrial fibrillation (PAF) , and to study the relationship between LAd and PAF. Methods; The studied subjects including 34 patients with PAF and 36 healthy controls. The PAF patients were divided into 2 groups: group A including 18 patients with idiopathic paroxysmal atrial fibrillation and group B including 16 patients with PAF companied by essential hypertension and/or coronary heart disease. Left atrial dimension ( LAd) was determined and the relationship between LAd and PAF was analyzed. Results: LAd in group A was not different (28. 69 ±5. 35) from that of controls (28. 08 ± 5. 93) (P >0. 05) , but there was a significant difference between the LAd measurements in group B and (38. 29 ±5. 89) controls (28. 08 ±5. 93) (P <0.05). Conclusions: LAd in patients with idiopathic paroxysmal atrial fibrillation does not change significantly, while LAd in PAF accompanied with essential hypertension and/or coronary heart disease increases.
