Is A Precise Mathematical Relationship Between Pulse Rate And Systolic Pressure
The systolic blood pressure (the larger or "top" number of a reading) measures the pressure of the blood coursing through a vessel at its peak. It is a function of both how dilated the blood vessels are overall, the amount of blood in those vessels, and the force of squeeze generated by the heart. This number is the primary target ...Read more
Related / separate: Blood pressure is a measure of the pressure of blood circulating in the arteries. The heart rate measures how many beats per minute the heart is squeezing. Generally, the heart rate will increase when the blood pressure begins to fall to maintain the same blood flow. A slower heart rate can make the blood pressure fall unless the volume of blood being ejected is large (such as in athletes). ...Read more

What is the safest range of a pulse pressure in a blood pressure? Is it really 30-60 difference between systolic and diastolic blood pressure?
Many factors. HT Pri: The pulse pressure is just 1 of many numbers on a blood pressure recording that has information for doctors. While the "normal" pulse pressure is about 40 mmHg, with a range you mentioned, a pulse pressure outside of that range may not be significant. In general, a high pulse pressure is worse than a low one, but it also depends on the NUMBER of the systolic (upper)reading. TTYD or HealthTap Prime ...Read more
Please advise what is the implication when there's a great difference between systolic pressure and diastolic pressure?

Relationship: The QRS complex on the ecg is the electrical activity associated with systole which is the mechanical squeezing of the heart which is the heart beat. The heart beat(systole) produces the pulse which is the surge of blood caused by the heart beat squeezing blood into the aorta. ...Read more
How important is pulse pressure(difference between systolic and diastolic) these days? do drs consider this an important indicator of cardiovascular disease?
Pulse pressure: Pulse pressure can be an important indicator of several characteristics of the cardiovascular system. It can help indicate the seriousness of aortic valve insufficiency and can indicate the state of peripheral vascular resistance and stroke volume relationship among other things. ...Read moreSee 3 more doctor answers
Complex question: When the left ventricle contract the aortic valve open and blood is pump to aorta. The peak pressure at that moment is systolic. When lt ventricle is relax the pressure at the aorta is called diastolic. Pulse pressure is the pressure to create the pulse and isthe difference between sys vs dias. Now, during 3 degree av block the lt ventricular filling will decrease and systolic wil decrease. ...Read moreSee 3 more doctor answers
Heart cycle: The heart is a pump that works in a cycle. Each heart beat has 2 components: systole when heart contracts to pump blood and diastole when heart relaxes to fill with blood. That is why each blood pressure measurement has 2 numbers: the upper one is systolic blood pressure and lower one is diastolic blood pressure. ...Read moreSee 1 more doctor answer
When tracking blood pressure, is the "mean" value the important part? I usually have a high systolic and low diastolic like 134/68 and heart rate 48.
Mostly systolic: The systolic pressure (upper number) is best understood in terms of what is normal and the relationship between BP and risk of stroke and heart disease. The diastolic pressure (lower number) seems to vary a lot depending on how the BP is measured (with a stethoscope or with an electronic BP cuff). The mean BP is rarely used outside the intensive care unit or the operating room. ...Read moreSee 2 more doctor answers
DPTI: It is a measure of coronary blood supply. Multiply the coronary perfusion pressure times the diastolic tmie. Cpp =diastollic blood pressure minus the left vetricular end diastolic pressure. Diastolic time is 60sec/heart rate-0.2seconds. The 0.2 is systolic time(fixed at 0.2s). Coronary flow occurs during diastole and relates to the pressure and how long diastole lasts. Now ask me what the evr is. ...Read moreSee 1 more doctor answer
