Methods A total of 26 pateints admitted to Zhongshan Hospital in Shanghai were enrolled, including 11 cardiac insufficiency patients and 15 control. Each subject was tested by non-invasive cardiac hemodynamic monitor immediately after echocardiography. Linear regression analysis and Bland-Altman consistency analysis were used in the analysis of relevance and consistency between two different methods. Results Linear correlation was shown on LVEF, SV, SVI, CO, CI, EDV, LVET and PEP/LVET , but not on PEP, betwe
