【摘  要】目的：研究高血压伴阵发性房颤患者的心脏超声临床特点。方法：选取我院2014年4月—2016年1月收治的88例高血压伴阵发性房颤患者，作为研究组；选择同期88例单纯高血压疾病患者作为对比组。两组患者均给予飞利浦IE33超声仪进行心脏超声检查，观察指标：患者左房内径、左室舒张末期内径、舒张早期心室快速充盈峰值速度/舒张晚期心房收缩峰值速度（E/A比值）、室间隔/左室后壁的差异。结果：研究组左房内径为（44.89±3.13）mm，明显比对比组（32.81±2.31）mm高，t检验统计学差异显著（t=12.824，P＜0.01）；研究组左室舒张末期内径为（43.82±12.42）mm，跟对比组（41.23±12.12）mm比较，t检验统计学差异不显著（t=0.342，P＞0.05）；研究组E/A比值为（0.82±0.21），明显比对比组（0.61±0.12）高，t检验统计学差异显著（t=5.924，P＜0.01）；研究组室间隔/左室后壁为（1.12±0.13），跟对比组（1.09±0.12）比较，t检验统计学差异不显著（t=0.241，P＞0.05）。结论：高血压伴阵发性房颤患者的心脏超声临床特点为左房内径明显增大，E/A比值增大，说明高血压伴阵发性房颤跟左心房扩大有密切关系，可因血压升高而导致心脏结构发生变化，引起形态学重构。

【Abstract】Objective:To study the clinical features of cardiac ultrasound in patients with hypertensionand paroxysmal atrial fibrillation. Methods:Experimentalobjects: 88 patients with hypertension and paroxysmal atrialfibrillation, admitted to ourhospital from April 2014 to January 2016, were selected as the research group; 88patients with hypertension during the same period were selected as the controlgroup, patients in both groups received cardiac ultrasound by using PHILPS IE33ultrasonic instrument. Observation indexes: the difference of the patients’ leftatrial diameter, left ventricular end diastolic diameter, peak velocity ofearly diastolic ventricular filling/ late diastolic peak atrial systolicvelocity (E/A ratio) and interventricular septum/posterior left ventricle.Results: The left atrial diameterof the research group was (44.89±3.13) mm, which was significantly higher thanthat of the control group, (32.81±2.31) mm, the difference was statistically significant byt test (t=12.824, P＜0.01). The left ventricular enddiastolic diameter of the research group was (43.82±12.42) mm, and that of thecontrol group was (41.23±12.12)mm, the difference was statistically insignificant byt test (t=0.342, P＞0.05). The E/A ratio of theresearch group was (0.82±0.21), which wassignificantly higher than that of the control group, 0.61±0.12, the difference was statistically significantbyt test (t=5.924, P＜0.01). Theinterventricular septum/posterior left ventricle of the research group was (1.12±0.13), andthat of the control group was (1.09±0.12), the difference was statisticallyinsignificant byt test (t=0.241, P＞0.05). Conclusion: The clinical features ofcardiac ultrasound in patients with hypertension and paroxysmal atrialfibrillation included the significant increasing of the patients’ left atrialdiameter and the E/A ratio, which indicated that the hypertension andparoxysmal atrial fibrillation was closely related to left atrial dilatation,the increasing blood pressure could lead to cardiac structure changes and causemorphological reconstruction.
