Does the entire heart have systole at the same time?

Q: Does the entire heart have systole at the same time, or do the atrias have it first? How does the whole low pressure thing? How do we know if the right side of the heart has low pressure or not, and why does it have low pressure?

A: When the ventricles are contracting, the atria are filling. Then when the ventricles relax, the blood in the atria enter the ventricles in preparation for the next contraction.

What is the difference between systole and diastole? How does this affect blood pressure?

Q: I think I understand the first part, but I was asked how this affect blood pressure. I really don’t understand that. If anyone has a user friendly explanation of this I would appreciate it. I have looked the cardiac cycle up on wikipedia already. I also have looked in a Biology Book. I don’t have an anatomy one handy.Thanks,

A: Systole is the squeezing of the heart to push blood out. It increases pressure in the arterial system.Diastole is when the heart relaxes and refills. The pressure decreases during this time, because the heart isn’t pushing any blood into the system.Here is a picture of an arterial pressure wave:http://web.missouri.edu/~huxleyv/Biophys5.GIFWhen we use an arterial line to measure blood pressure, we see it as a continuous tracing. That picture shows you how blood pressure goes up and down with each heartbeat. Cuff pressures just give a snapshot view of the peak and trough of the wave.You can feel the result of the heart pushing blood into the arterial system when you take your own pulse.
