【摘要】 目的应用全方向M型超声心动图探讨原发性高血压患者左室局部心肌功能与颈动脉波强度之间的关系。方法高血压组30例，正常组30例。应用全方向M型超声系统测量两组左心室短轴乳头肌水平6个节段收缩期运动速度达峰时间（Ts）及舒张早期运动速度达峰时间（Td），应用Aloka α-10型超声诊断仪测量波强度参数W1，研究乳头肌水平各壁收缩期运动速度达峰时间（Ts）均值与波强度W1的关系。结果1.高血压组前壁、侧壁、后壁、前间隔、后间隔Ts小于对照组（p<0.01，表3），其他节段差异无统计学意义（p>0.05，表3）；2.高血压组左室侧壁、前间隔Td大于对照组（p<0.01，表3），其他节段差异无统计学意义（p>0.05，表3）；3.高血压组W1值较对照组升高，差异有统计学意义（p<0.01，表4）；4.乳头肌水平各壁收缩期运动速度达峰时间（Ts）均值与W1无明显线性相关。结论全方向M型超声心动图的时间参数能够反映原发性高血压患者局部心肌功能的改变；高血压患者局部心肌功能与颈动脉波强度无明显线性相关。更多还原

【Abstract】 [Abstract] Objective to assess hypertension patients the relationship betweenregional function of the left ventricle and the carotid artery Wave intencity.Methods:A total of30healthy subjects and30subjects with hypertension were included.Thetime to peak myocardial systolic velocity(Ts) and the time to peak myocardialearly-diastolic(Td) were obtained from the velocity-time curves of6segments of theleft ventricular short axis view at the level of papillary muscles with OME,which wereused to compared the changes of cardiac systolic and diastolic function of the twogroups.The magnitude of W1,and the length of R-W1interval as well as W1-W2interval were recorded by WI technique applied on the left carotid artery of eachpatiend,and assess the relationship between the the time to peak myocardial systolicvelocity(Ts) and W1.Results:1. Compared with that of the normal group,Td of the hypertension was significantlylonger in the lateral segments and antereroseptal(p<0.05).2. Compared with that of the normal group,Ts of the hypertension was significantlyshorter in every segments except inferior wall(p<0.05).3. W1in primary hypertension group increased compared with those of normalcontrols(p<0.05).4. W1was not correlated with the Ts mean of each wall.Conclusion:Omni-directional M-mode echocardiography can reflect the changes of the regionalsystolic function of the hypertension patients.更多还原
