However, the number of studies supporting the existence of the inverse relationship between blood pressure reduction, especially diastolic pressure lowering, and cardiovascular morbidity and mortality, is increasing each year. The aim of this review is to summarize current knowledge about the J curve ...
Unlike high blood pressure, low blood pressure is defined primarily by signs and symptoms of low blood flow and not by a specific blood pressure number. Some individuals routinely may have blood pressure numbers of 90/50 with no symptoms and therefore do not have low blood pressure. However, ...
Bleeding decreases the number of red blood cells in the blood stream and leads to a decreased amount of fluid in the intravascular space and low blood pressure. Low Blood Pressure and the Arterial Wall The space within the intravascular space is variable, based upon the muscle tension in the ...
Blood pressure, or the force exerted by your circulating blood against artery walls, is measured using two numbers: Systolic, or the top number. This number measures how much pressure the blood is exerting against the artery walls when the heart beats. Diastolic, or the bottom number. This nu...

The second number is diastolic blood pressure, the pressure against the inner walls of your arteries as the heart relaxes. 第二个数字是舒张压,心脏舒张时对你动脉内壁产生的压力。 Normal blood pressure is generally considered to b...
A blood pressure reading appears as two numbers. The top number is a measure of systolic pressure, or the pressure in the arteries when the heart beats and fills them with blood. The bottom number measures diastolic pressure, the pressure in the arteries when the heart rests between beats. ...

When a blood pressure reading is taken, two pressure levels are measured: systolic (the pressure during a heartbeat) and diastolic (the pressure between heartbeats). These measurements are typically recorded as one number over the other (e.g., 120/80 mmHg) with both values represented in mill...
