【摘 要】目的：探究高血压合并阵发性心房颤动患者的心脏超声图像特征和诊断价值。方法：此次实验对象全部选自本院2017年1月至2018年12月之间接收的38例高血压合并阵发性心房颤动患者，将其归为实验组，同时将同一时期的38例高血压患者归为对照组，两组患者全部使用心脏超声检查，并分析图像特征。结果：在尖瓣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）、左室舒张末期内径（LVEDd）指标上，实验组全部高于对照组，差异有统计学意义（P<0.05）；在舒张期室间隔厚度/舒张期左室后壁（IVSd/LVPWd）、左房内径（LAD）指标上，实验组全部高于对照组，差异有统计学意义（P<0.05）。结论：心脏超声用于高血压合并阵发性心房颤动患者，不仅可以清晰反应心脏形态结构变化，还可以根据生理指标判断左心房扩大情况。

Department of Ultrasound Diagnosis， Zhuhai Hospital of Integrated Traditional Chinese and Western Medicine， Guangdong Zhuhai 519000， China【Abstract】Objective：To explore the features and diagnostic value of cardiac ultrasound images in patients with hypertension and paroxysmal atrial fibrillation.Methods： The subjects of this experiment were all selected from 38 patients with hypertension and paroxysmal atrial fibrillation received in our hospital between January 2017 and December 2018，they were classified into the experimental group， and 38 patients with high blood pressure during the same period were classified into the control group. All patients in the two groups were examined by echocardiography and the image characteristics were analyzed.Results： The experimental group was higher than the control group in terms of the peak rapid ventricular filling velocity in the early diastole/peak atrial contraction velocity in the early diastole （E/A） and the left ventricular end-diastolic diameter （LVEDd） indicators， and the difference was statistically significant（P<0.05）； In terms of the diastolic ventricular septal thickness/ diastolic posterior left ventricular wall （IVSd/LVPWd）， left atrial diameter （LAD） indicators， the experimental group was all higher than the control group， the difference was statistically significant（P<0.05）.Conclusion： The use of echocardiography in patients with hypertension and paroxysmal atrial fibrillation can not only clearly reflect the changes in the shape and structure of the heart， but also judge the enlargement of the left atrium based on physiological indicators

隨着生活结构的改变和社会人口老龄化的加重，致使老年慢性疾病发病率不断提升。临床中常见的慢性心血管疾病之一为高血压，存有较高的发病率，据相关调查数据显示，高血压发病人数大致有2亿[1]。此种疾病病程较长，会诱发多种疾病，如脑卒中、心功能降低、心力衰竭以及心脏结构重塑性代偿性肥大等[2]。且部分高血压患者还会合并阵发性心房颤动，心房颤动属于一种心律失常症状，通常是由于心房主导折返环引起的，会严重损伤患者机体健康和生命安全。且此类患者会发生病理性改变，通过心脏超声检查可显示其心脏生理变化。……
