Systolic blood pressure is when the left ventricle contracts (first number), diastolic pressure is when the left ventricle relaxes (second number).

What does the 3 numbers blood pressure reading mean?
The upper reading is the systolic blood pressure while the lower reading is the diastolic blood pressure. Systole is the contraction of the heart while diastole is the relaxation of the heart.
Why is systolic Blood pressure higher than your diastolic Blood pressure?
"Systolic" pressure is the pressure in the circulatory system when the heart contracts to pump everything along. "Diastolic" pressure is what's left over in the system when the heart is completely relaxed.
What is low pulse rate in ECG?
diastolic pressure
Is end-diastolic volume greater when the heart rate is 90 beats per minute or 150 beats per minute?
No, the end diastolic volume does not with your heart rate. The end diastolic volume decreases as your heart rate increases. End diastolic volume is the amount of blood that is in the ventricles during diastole.
What herb can improve heart function?
Hawthorn helps the heart's pumping action, slows rapid heart rate and strengthen a failing heart. Hawthorn usually lowers high blood pressure, especially a raised diastolic high blood pressure
Increased heart rate causes systolic pressure to increase or decrease mean arterial pressure?
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.
Why is there no increase in diastolic pressure after exercise?
Diastole is a stage in which the heart is completely relaxed in order for blood to pour into the heart's atria (upper chambers). Although the rate at which the blood enters the heart increases (causing a slight increase in pressure), there is no contraction for the pressure to increase drastically.
Does blood pressure affect heart rate?
Does blood pressure affect your heart rate? Regular heart rate is 60-100. Increase in heart rate within this normal range increases cardiac output and blood flow/volume; therefore, increases blood pressure. In healthy people, even with heart rate increase, there is not an important spike in blood pressure, because healthy vessels will dilate to accommodate more blood flow. The increase in blood pressure is usually small and doesn't pose risks. Increased heart rate and cardiac output decreases blood pressure if heart rate is extremely high. When heart rate is high (out of normal range 60-100 beats per minute), there is no time for the heart to fill with blood (preload) resulting in low stroke volume; therefore, reduced blood pressure. Remember, the heart spends more time in diastolic (preload time) than systolic (contraction of the heart). When heart rate is too high, this normal diastolic time is reduced which contribute to low stroke volume and low blood pressure. stroke volume is affected by Preload, Afterload, and Contractility
What do the 2 numbers of blood pressure represent?
The top number is the Systolic pressure. The bottom number is the Diastolic pressure. The top number is the force that the blood puts against the artery walls as the heart pumps. The bottom number is the pressure against the artery walls as the heart rests in between beats.
Can you have a heart rate of 280 over 180?
Um, you may be thinking of Blood Pressure... If so a Systolic Blood Pressure of 280 over a Diastolic Blood Pressure of 180 is possible, albeit pathologic.
What happens to end diastolic volume when an increase in heart rate is not accompanied by an increase in contractility?
end diastolic volume is decreased
What happens to end diastolic volume when an increase in contractility is not accompanied by an increase in heart rate?
end diastolic volume is decreased
