检测方法分创伤性和无创性两类。其中无创血流动力学监测包括阻抗血流图、超声心动图和核医学等。其是基于心衰患者心排血量少、射血分数降低、心脏指数降低、心室舒张末压力升高和外周血管阻力增加的共同特点来监测。

Detection of invasive and noninvasive categories. Where non-invasive hemodynamic monitoring, including ICG, echocardiography and nuclear medicine. It is based on fewer cardiac output in patients with heart failure, ejection fraction, cardiac index decreased ventricular end-diastolic pressure increased peripheral vascular resistance and increase the common characteristics to monitor. Currently more than the basis for the diagnosis of heart failure in patients with clinical symptoms, signs, medical history relevant test results, for the non-typical symptoms or diagnosis of asymptomatic patients with heart failure there is a certain degree of difficulty, however, changes in cardiac pump function through hemodynamic monitoring but its indicators are specific changes [13]. 

故其可作为了解心脏功能状态和早期诊断心衰提供客观依据，还可作为心衰经治疗过程中疗效的判断，通过治疗前后的心功能参数的比较来观察药物的疗效，为治疗方案的制定和调整，药物的选择提供参考依据。

Therefore, it can be understood as a state of cardiac function and early diagnosis of heart failure to provide an objective basis, but also as a failure by the judge the efficacy of the treatment process, through the treatment of cardiac function parameters before and after comparison to observe the effect of drugs, for the treatment plan and adjustment, the drug of choice to provide a reference.

目前诊断左心室功能不全的重要指标是心脏彩超，但其短期变化的敏感性及其检查的便利性不及血流动力学监测。血流动力学监测系统可以实时和连续监测患者病情，本研究监测的血液动力学参数可以使患者的血液动力学状况和心室功能得到实时的反映、评估。

The diagnosis of left ventricular dysfunction is an important indicator of cardiac ultrasound, but its sensitivity to short-term changes and convenience checks less hemodynamic monitoring. Hemodynamic monitoring systems in real-time and continuous monitoring of the patient's condition, the study monitored hemodynamic parameters can make the patient's hemodynamic status and ventricular function was reflected in real-time to assess. Detecting indicators CI, CO, SV, SI and other representatives of the cardiac output, STR represents myocardial contractility, TFC represents preload, SVRI, SVR behalf cardiac afterload. TFC thoracic electrical conductivity means for indicators to determine cardiac preload, the value marked worsening heart failure prompted increased, the amount of thoracic fluid accumulation. TFC thoracic fluid volume and by value change can determine the effectiveness of clinical treatment. STR is the reaction cardiac pump function and cardiac contractility index, representing cardiac electrical excitability of the ratio between the systolic and mechanical. STR associated with LVEF collect research data at home and abroad, STR and LVEF were negatively correlated [10], which can be used as anti-heart failure drug of choice as well as evaluating the prognosis of heart failure reference index. STR values increased heart failure. STR values can be measured and thus prompt a certain extent, timely understanding of early left ventricular systolic function in patients with heart failure [11]. This study shows that between different syndromes noninvasive cardiac function parameters significant difference between, CI, CO distributed among the groups in order to cardiopulmonary Qi Group 本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
