Based on observing the complete cardiac cycle, the synchronized body surface electrocardiogram and the time-flow curves for the mitral valve orifice and aortic valve orifice were used as the evidence of phase confirmation to determine the four observation phases: early and middle diastole (ED, MD), isovolumic contraction (IC), and rapid ejection (RE). The height, weight, body surface area, and diastolic blood pressure in males were higher (P < 0.05); while age, body mass index, and systolic blood pressure were not significantly different (P > 0.05). The establishment of normal reference values for echocardiographic VFM that can be widely accepted in clinical practice has important scientific and theoretical significance for future studies of abnormal cardiac fluid dynamics and has significant clinical significance for identifying normal and abnormal fluid dynamic status in the LV chamber. [...]carrying out a multicenter, large-sample, quantitative study is an effective method to test the practicability and reliability of the technology, and it is conducive to the establishment of VFM-based, novel, and standardized guidelines for cardiac hydrodynamic function. [3,4] If the same normal reference values are used as the fluid dynamic parameters for the male and female, the results will be biased, and false positives and negatives that could have been avoided will occur. [...]in this multicenter study, we observed the VFM parameters in males and females to provide objective, accurate, and representative normal reference values of VFM parameters for Chinese adults.
