  Notes:
The wristtype electronic sphygmomanometer is sensitive, so it is necessary to maintain a correct sitting posture during the measurement process. 
After 5-10 minutes of rest, keep breathing evenly, and the measurement site and the heart site should be at the same level. 
Usually, the measurement of the wrist is higher than the measurement of the heart, which results in a lower blood pressure value and a lower level than the heart
