What is the cause of low pressure when measuring blood pressure

Low pressure refers to diastolic blood pressure, high blood viscosity, high blood pressure and other conditions caused by high emotional excitement, specific analysis is as follows:

1. emotional excitement

When the patient is emotional, the sympathetic nerve will be abnormally excited, resulting in faster heart rate, so that blood pressure in the blood vessel wall flow speed increases, thus causing the above situation.

2. high blood viscosity

If the patient's blood viscosity is high, it will cause blood flow speed to slow down, resulting in reduced blood flow, at this time there will be diastolic pressure increased.

3. hypertension after high blood pressure

, blood flow in the blood vessel wall pressure will increase, resulting in increased blood pressure, will lead to this phenomenon.
