心房扑动与左、右心房扩大的关系

Relationship between atrial flutter and enlargement of right and left atria

目的探讨心房扑动与双心房扩大的关系。方法对2006年1月～2010年3月在我院住院的1159例心房扑动者,通过彩色超声心动图(UCG)测量心脏左右心房内径,研究与相应疾病的关系。结果 1159例心房扑动者男性多于女性。冠心病者538例(占46.4%)。UCG测量左心房内径值为28～79(平均57.87±10.11)mm。右房内径值为32～68(平均46.32±9.53)mm。其中850例左心房内径≥38mm及或右心房内径≥40mm,与内径正常者比,有统计学意义。结论提示心房扑动与左、右心房扩大相关。左心房扩大例数与右心房扩大例数比,有统计学意义,提示左房扩大比右房扩大明显。

Objective To study the relationship between atrial flutter and the bi-atrial enlargement. Methods Total of 1159 patients hospitalized from January,2006 to March 2010 were studied.The diameter of right and left atria were measured by cardiac eco-graphy.The relationship with various diseases was studied. Results There were more male patients in 1159 atrial flutter cases,538(46.4%) patients had coronary heart diseases.The left atrial diameter averaged 57.87±10.11 mm,ranged from 28 to 79 mm.The right atrial diameter 46.32±9.53 mm,ranged from 32 to 68 mm.The left atrial diameter ≥38 mm and right atrial diameter ≥40 mm were found in 850 patients.There were significant differences between normal atrial diameter and left atrial enlargement or right atrial enlargement. Conclusion There were more patients with left atrial enlargement than those with right atrial enlargement,it suggests left atrial enlargement is more profound.
