Abstract：Objective To estimate the normal range of pulse wave transit time (PWTT) about the middle aged and elderly people,
and to provide the basis for the prediction of the vascular sclerosis at early stage. Methods The convenience sampling method was
adopted in our hospital outpatient, and 1288 cases of healthy middle aged and elderly people were recruited into this research. The
PWTT collected by smart watch was analyzed statistically. Results The 95% confidence interval (CI) ranged from 186 to 192 ms in
group 35~44; The 95% CI of men ranged from 180 to 186 ms, and women ranged from 185 to 190 ms in group 45~59; The 95% CI
ranged group from 177 to 183 ms in 60~89. The difference among these three groups was significant (P<0.05); group 45~59 was 4 ms
shorter than that of the group 35~44 (P<0.05); group 60~89 was 5 ms shorter than that of the group 45~59. Conclusion The degree of
arteriosclerosis in middle aged and elderly people gradually increases with age, and the older the age, the faster the arteriosclerosis.
