Normal range of high and low blood pressure difference

High and low blood pressure generally refers to systolic blood pressure and diastolic blood pressure. The normal range of systolic and diastolic blood pressure difference should be between 30-40mmHg.

The difference between systolic and diastolic blood pressure is generally called pulse pressure difference. Pulse pressure difference can reflect the elasticity and blood volume of blood vessels in the body. When pulse pressure difference is greater than 60mmHg, it is generally called pulse pressure difference increase, which may be caused by hyperthyroid heart disease, aortic insufficiency, etc. When pulse pressure difference is less than 20mmHg, it can be called pulse pressure difference decrease, mostly caused by pericardial effusion, constrictive pericarditis, etc.

When pulse pressure difference is abnormal, it is necessary to seek medical treatment in time to control the development of the disease.
