Pulse pressure difference of 20~40mmHg is the normal range, >60mmHg is increased pulse pressure.
Differential pulse pressure, referred to as pulse pressure or differential pressure, is the difference between systolic pressure and diastolic pressure, the normal range of differential pulse pressure should be 20~40mmHg. Pulse pressure is related to cardiac output per beat, heart rate, peripheral resistance, and the elasticity of the walls of large arterial vessels, etc. In general, pulse pressure >60mmHg is considered to be elevated.
Generally speaking, a pulse pressure of >60mmHg is an increase in pulse pressure, which can be seen in atherosclerosis, hyperthyroidism, aortic valve insufficiency, severe anemia, etc., while a pulse pressure of <20mmHg is a decrease in pulse pressure, which can be seen in heart failure, aortic stenosis and other diseases.
It is recommended to pay attention not only to the systolic and diastolic blood pressure values, but also to the pulse pressure value when measuring blood pressure, and any abnormality should consult a specialist in time.
