What reason is blood pressure of left and right hand different

Left and right hand blood pressure is different, depending on which hand you are. It depends on which hand is the forehand. The main working side often has high blood pressure because of thick blood vessels.

Some people have had surgery on one side, or have been injured, damaged blood vessels, so the amount is low.

There are also people like hemiplegia on one side. Due to thrombosis and long-term inactivity, their blood pressure will be much lower than that on the better side. There are also congenital heart disease, such as coarctation of aorta, patent ductus arteriosus, leading to hemodynamic changes, there will be low blood pressure in the left upper limb.

matters needing attention

The difference of left and right hand blood pressure may also be the error of stethoscope. In order to reduce the error, it is suggested to touch the place where the brachial artery beats strongly before measuring blood pressure, then place the cuff for measuring blood pressure, and put the stethoscope in the place where the brachial artery beats strongly.
