During atrial fibrillation: O A. The EKG shows no discernable P wave. O B. There is a noticeable decrease in the regularity of beating. O C. The ventricle continues to maintain cardiac output. D. None of the above.

Which of the following is/are involved in regulating blood pressure? a. heart b. baroreceptors c. cardiovascular center in medulla oblongata d. all of the above

The maximum amount of blood within the left ventricle just before the start of isovolumic contraction is called the ____________________ (EDV, ESV, EF).  The amount of blood found within the left ventricle just after ejection and before the left AV valves opens is called the _____________________ (EDV, ESV, EF).  Clinically, one of the best parameters used to measure cardiac function is the EF.  In terms of EDV and ESV, what simple equation would give you the EF?  If you had an echocardiogram and found that your EDV was 100 cc and your ESV was 30 cc, what would be your EF?  EDV = end-diastolic volume, ESV = end-systolic volume, EF = ejection fraction

Once you have studied the wiggers diagram   Create your own outline of the steps with a brief explanation of each step. Why each step occurs when it does; example p-wave occurs before atrial contraction becasue it is the indication that electrical current traveled through the atria to cause atrial depolorization. You should cover all major steps from start to end of a single cardiac cycle. number of steps you include are up to you depending on how you are looking at it, but make sure all major steps are covered
