How does heart rate affect blood pressure?

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
