Abstract Objective: Full-volume imaging(FVI) was used to detect the synchronism of left ventricular volume and ventricular systolic function in normal adults of different ages, and to explore the influence of age on it. Methods: In the hospital physical examination center, there were 126 healthy adults on examination who were divided into the youth group(43 cases, 21 male and 22 female, age 18~45 years old), the middle-aged group(42 cases, 22 male and 20 female, 46~64 years old) and elderly group(41 cases, 22 male and 19 female, age 65 years old or higher) by age. After routine echocardiography, conventional echocardiography values were obtained. After connecting with the electrocardiogram, a 4V probe was used to collect the dynamic four-chamber cardiotomy surface of the apex of the heart and obtain the full-volume image of the left ventricle for online with FVI analysis. Results: Compared with the youth group, the measured values of M-type ultrasound ejection fraction(EF) in the middle-aged and elderly groups gradually decreased with the increase of age, and the difference was statistically significant(P<0.05). Compared with the youth group, the SV of each stroke in the middle-aged group and the elderly group gradually decreased with the increase of age, and the difference was statistically significant(P<0.05). The total volume EF measured value decreases with age, which is related to the M-type measured value. The correlation coefficient is 0.415. Compared with young and middle-aged group, the systolic dyssynchrony index(SDI), dispersion in end systole(DISPES), pre-contraction time volume(Pre Contr) was statistically increased in elderly group(P<0.05). Conclusion: As the age increases, the EF value decreases and the risk of left ventricular systolic dyssynchrony increases.
