超声测量技术在心血管机能研究中的应用与评价

本文扼要介绍了超声测量技术的原理、方法及其应用。与急性实验比较,它具有不受麻醉、损伤的影响,动物处于生理状态下,仪器灵敏度较高,数据较精确,可同步记录室壁收缩状态与心功能各参数的变化,便于作精确的相关分析等优点。适于生理、药理及病理生理学心血管机能的慢性实验研究。

APPLICATION AND EVALUATION OF THE ULTRASONIC TECHNIQUE IN STUDY OF CARDIOVASCULAR FUNCTION

The principle method and application of the ultrasonic technique are briefly recommended. As compared with acute experiment, this technique has the following merits: the determination is not affected by anesthesia and damage, the animal is in physiologic state, the sensitivity of apparatus is heigher, the result is more accurate, the changes in the contractory state of the ventricular wall and the parameters of cardiac function can be recorded synchronously, and the correlation analysis can be made more accurately. This method is suitable for chronic cardiovascular function experiments of physiology, Pharmacology and pathophysiology.
