A typical heart rate is 75 beats per minute (bpm), which means that the cardiac cycle that produces one heartbeat, lasts for less than one second. The cycle requires 0.3 sec in ventricular systole (contraction)—pumping blood to all body systems from the two ventricles; and 0.5 sec in diastole (dilation), re-filling the four chambers of the heart, for a total of 0.8 sec to complete the cycle. WebBlood Pressure Regulation and Shock Blood pressure is tightly controlled. Homeostatic mechanisms assure that blood pressure does not get too low or life sustaining organs like the brain can be in danger of permanent damage. You may hear the term Pulse Pressure.
