What Is The Difference Between Systolic And Diastolic Pressure
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
Pulsatile flow: Blood flows through the arteries in a pulsatile fashion, propelled by rhythmic contractions of the left ventricle. The pulsatile flow means that the pressure is higher in systole (when the heart contracts) and lower in diastole (when the heart relaxes). Systolic pressure is the peak pressure and diastolic pressure is the lowest pressure. ...Read more
Arteries and veins: Systolic pressure is the pressure in your artery during during cardiac contraction as blood rapidly flows into the arteries . It measures to certain degree the elasticity of the vessel . Diastolic pressure is the pressure after contraction when no active flow is going and measures the resting tone of the artery . CVP is the venous pressure closest to the heart or the vena cavae. ...Read more
Please advise what is the implication when there's a great difference between systolic pressure and diastolic pressure?

Pressure in arteries: The pressure in the arteries when the heart contracts is the systolic blood pressure and when it relaxes the pressure is the diastolic pressure. It could be measured directly by putting a needle into an artery or indirectly with a blood pressure cuff. ...Read moreSee 1 more doctor answer
See doc, likely meds: Elevated systolic and diastolic BP implies likely needs for meds to control bp. If elevations are borderline high (130-140/80-90), would suggest checking at home, and then consider weight loss, alcohol and salt restriction to help. If frequent rechecks still show BP often in excess of 140/90, need to start med, along with physical exam and lab tests. ...Read more
A little high: I am assuming you mean systolic of 130, not 13. A systolic of 130 is normal for most people but there are some conditions where we would like it a bit lower. Diastolic blood pressure should definitely be below 90 and 80 would be even better. A single measurement of a high blood pressure is not concerning but if the diastolic stays high you should see MD. Also avoid salt, caffeine and alcohol. ...Read moreSee 1 more doctor answer
