this is how long ventricles remain repolarized after undergoing an action potential and is the same duration as ventricular diastole. The mitral and tricuspid vales are open and the aortic and pulmonary valves are closed 5 Question #5: What is the name for this pulsatile noise, and what causes it to occur? Korotkoff; the cuff pressure causes the underlying artery to collapse and then reopen with each heartbeat 6 Question #6: What is the blood pressure reading you just obtained? 136/78 7 Question #7: What happens to each of the intervals measured in the cardiac cycle activity (P-R interval, R-R interval, R-T interval, and T-R interval) as heart rate increases or decreases? What parts of the cardiac cycle change, and what parts remain the same? In your answer, include discussion of the major electrical junctions of the heart. The PR interval increased when the heart rate increased; The other intervals stay the same. The PR interval indicates how long it takes electrical signals to travel from the atria to the ventricles. In the R-T interval, the ventricles remain in a depolarized state. The D-R indicates

4/12/2020 Results 2/3 how long the ventricles remain in a polarized state in between depolarizations, and the S-T is the section that may be elevated as a result of a heart attack. 8 Question #8: What effect does heart rate have on cardiac output, and why? How is this reflected in the changes in blood pressure when we keep the peripheral resistance (PR) constant? Does this mirror what we see in real life, and if not--what
