Whereas Systolic pressure means the peak in blood pressure when your heart contracts, Diastolicpressure is the pressure when your heart relaxes, between beats.
Low diastolic pressure usually means a low total volume of blood in the vascular system for the heart to pump. The most common causes of this would be dehydration or hemorrhage.
what does it mean when systolic pressure is high and diastolic pressure is low
Heart failure
The
Mean arterial pressure can be thought of as 1/3 systolic + 2/3 diastolic since the heart spends slightly more time is diastole (rest) that it does in systole (contracting). MAP = 1/3 systolic + 2/3 diastolic. Therefore, an increase in either systolic or diastolic will increase the MAP. Additionally, under physiological conditions, an increase in heart rate will increase blood pressure. Increased HR leads to increased cardiac output, among other things, which increase blood pressure.
The ventricles contract to pump blood out of the heart.
Blood pressure is a two-number measurement of your heart's function. The top number is the systolic pressure, or the pressure of the blood within the vessels as your heart contracts. The bottom, or diastolic, number is the pressure of blood between the heartbeats, or when your heart rests and refills. The National Heart, Lung and Blood Institute sets the target range at less than 120/80.
A complication of a low heart rate or "Bradycardia" is high blood pressure.
Do you mean a drawing "pen?"
Pulse Pressure....(Systolic Pressure-Diastolic Pressure)
Your heart is about to explode and you die
[Systolic Blood Pressure+(2 x Diastolic Blood Pressure)]/3
Mean Arterial Pressure (MAP) is the mean of pressure you would obtain if you took measurements in several intervals during the cardiac cycle. Ex. systolic pressure + 2x Diastolic pressure/3 120/80= 120 + 2(80)/3= 93mmHG ( approximately)
That means you have high blood pressure systolic should be around 90-140 diastolic should be around 60-90
What does the BP numbers mean? The number on the top is the systolic blood pressure and the number on the bottom is the diastolic blood pressure. The systolic BP is the pressure in the arteries right when the blood is pumped out of the heart, therefore the pressure is bigger. The diastolic BP is the pressure in the arteries after the blood has been pumped out and before the next heart contraction. At this moment, the heart is relaxed and the pressure is much lower.
80 mm Hg
Is this systolic (the number on the top) or diastolic (the second number or the one on the bottom)? If this is a mean systolic blood pressure then it is absolutely fine, and nothing to worry about. A diastolic pressure of this level should be controlled using medications, as it can increase your risk of heart attack, stroke, peripheral vascular disease and various other problems. If this is the case, you should see your doctor about bringing your high blood pressure under control.
A dogs normal blood pressure is 140mm systolic, 100 mean, and 75mm Diastolic. Just like in humans pets that are overweight or on poor diet can suffer from high blood pressure.
The best or most common description for systolic pressure would be that its related to your blood pressure. If you have systolic blood pressure it could mean that your blood vessels are clogged up.

In normal health care two types of blood pressure is messured; the diastolic and the systolic. The systolic blood pressure is the pressure the heart generates when it contracts and sends out a pulse of blood through the arteries. The diastolic pressure is the pressure that resides in the arteries between heartbeats. Typical systolic pressure: 120 mmHg Typical diastolic pressure: 80 mmHg. Another way of measuring blood pressure is by calculating mean arterial blood pressure MABP. This is calculated by the formula: MABP = 1/3 SBP + 2/3 DBP SBP & DBP being systolic and diastolic blood-pressure. For a person with 120 / 80 mmHg the mean arterial blood pressure (MABP) will be: MABP = (1/3x120) + (2/3x80) = 93mmHg. The reason for the systolic being 1/3 and the diastolic being 2/3, is that the systolic only presides for 1/3 of the time. The rest of the time, between two pulses, the diastolic pressure rules, and that's why it's 2/3.
