What Is A Diastolic Pressure Time Index
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
Nope: Some people who walk around and feel well have diastolic bps of zero. (at least as estimated by a BP cuff which is an indirect measurement). My only caveat: get an echo and be sure you don't have aortic regurgitation which can be severe, cause no symptoms for years, and be hard to detect with a stethoscope. ...Read more
Vascular tone: Both systolic and diastolic pressures are significantly impacted by the level of vascular tone or "resistance" or restriction to a given rate of blood flow. Although we have excellent medication options for managing vascular resistance, I have found that good cardiovascular conditioning seems to positively impact the diastolic blood pressure by enhancing "run off" in the peripheral vascular bed. ...Read moreSee 1 more doctor answer
Several reasons: Most high blood pressure is idiopathic (no reason, you just have it) whether it is systolic or diastolic. It runs in families so if your parents have it, you are more likely to get it. There are occasion cases secondary to specific causes such as adrenal tumors, kidney problems, or narrowing of the aorta (called coarctation) and that is called secondary hypertension. ...Read moreSee 1 more doctor answer
Why would you?: A low diastolic blood pressure could be due to leaking of the aortic valve or other problems so finding the cause is important. If you feel well, a low pressure, diastolic or systolic, may not be a bad thing. People with relatively low blood pressure live longer. And, how low are you talking about? ...Read moreSee 2 more doctor answers
Artery Stiffness: The diastolic blood pressure or the "bottom number" when the blood pressure is taken is when the pressure at which the heart beat is no longer heard by the stethescope. It is related to the stiffness of the arterial tree in the body. The stiffer the artery the higher the diastolic pressure. ...Read moreSee 2 more doctor answers
Whenever you want: Diastolic blood pressure refers to the pressure in the arteries during the period of heart's relaxation, i.e. Once it finished ejecting blood during contraction. For every single heart beat, there is the period of contraction ("systolic blood pressure") and the relaxation ("diastolic"). In any single cardiac cycle, each of these arterial pressures can be measured. ...Read moreSee 1 more doctor answer
