Pulse pressure is the difference between the systolic and diastolic pressure readings. It is measured in millimeters of mercury (mmHg). It represents the force that the heart generates each time it contracts. If resting blood pressure is (systolic/diastolic) 120/80 millimeters of mercury (mmHg), pulse pressure is 40. pulse pressure is considered abnormally low if it is less than 25% of the systolic value. The most common cause of a low (narrow) pulse pressure is a drop in left ventricular stroke volume.
What is pulse pressure and why are people talking about it? Pulse pressure refers to the difference between the systolic (top) and diastolic (bottom) blood pressure. If your blood pressure (BP) is 120/80, for instance, your pulse pressure is 120 - 80 = 40 mmHg. A pulse pressure of 40 mmHg is normal. Why does this matter? Does it add important information beyond knowing just your systolic and diastolic values?
