摘要：
In the measurement device, the blood pressure of the upper arm and the blood pressure of the lower limb are measured using cuffs attached to the upper arm and the lower limb (ankle), respectively. The pulse wave of the upper arm and the pulse wave of the lower limb are measured in synchronization using such cuffs. The upper arm-lower limb pulse wave propagation velocity (baPWV) is calculated based on the appearance time difference of the two pulse waves. The upper arm pulse wave propagation velocity (upper arm PWV) is calculated based on the appearance time difference of the ejection wave and the reflection wave in the upper arm pulse wave. If the values of such propagation velocities are different, a warning is issued.
