测定心脏功能的意义心脏的主要功能是推动血液循环。人能胜任多少体力活动,往往与心脏功能是分不开的。在选拔海、空军等体质要求较高的战士和需经受得起繁重体力负荷的运动员时,在评定运动锻炼效果和药物疗效时,都需要有一个客观的心功能评价标准。心血管疾病在各国都是常见病,如能早期发现、早期治疗,就会大大降低死亡率。心功能的测定可用于一些心血管疾病的早期或辅助诊断,也可用于心肌梗塞的监护及预后估计。因此,心脏功能的测定对部队选兵、保健和临床诊断、疾病防治都有十分重要的意义。测定心功能的方法心功能的检查方法分为创伤性(侵入性)和无创伤性(非浸入性)两大类。创伤性方法以心导管检查为主,即将心导管经周围静脉送到心脏的右侧各心腔或经动脉逆行插入左侧心脏,抽取血液标本进行氧含量的测定,测量心腔内的压力曲线,观察心(?)
The significance of determining cardiac function The main function of the heart is to promote blood circulation. How many physical activities a person can perform is often inseparable from cardiac function. In the selection of the sea and air forces and other physical requirements higher warriors and need to withstand heavy physical exertion athletes in the assessment of the effectiveness of exercise and drug effects, both need to have an objective assessment of cardiac function. Cardiovascular disease is a common disease in all countries, and early detection and early treatment will greatly reduce the mortality rate. The determination of cardiac function can be used for some early or secondary cardiovascular disease diagnosis, monitoring and prognosis of myocardial infarction can also be used to estimate. Therefore, the determination of cardiac function is of great significance to troops selection, health and clinical diagnosis, disease prevention and treatment. Heart function test methods Heart function test methods are divided into traumatic (invasive) and non-invasive (non-invasive) two categories. Traumatic approach to the main cardiac catheterization, the heart catheterization is about to the right heart of the heart through the ventricles of the heart or by retrograde artery into the left heart, blood samples were taken for determination of oxygen content, measurement of intra-cardiac pressure curve , Observe the heart (?)
