Post lab 8 cardiovascular effects of exercise

1. Which ECG intervals changed after exercise? why?

2. Which ECG intervals did not change much after exercise? why?

3. What relationship do you observe (or should have observed) between exercise and HR?

4. Did individuals that exercise more regularly recover from aerobic activity faster than those that do not?

5. Why would blood flow to the finger go down after aerobic exercise even though systemic blood pressure rises?

6. How did blood flow to the finger change after the hand exercise? were the result similar to peripheral blood flow after aerobic exercise? why?

7. How do you think peripheral blood flow were to change if an individual was at rest and digesting a big meal ? why?

8. Patients with hypocalcemia often show an elongated ST segment. using your knowledge about the role of calcium in heart contraction, explain why this specific segment an ECG is affected?

9. Patients with hyperkalemia often show abnormal (often peaked) T waves. using your knowledge about the role of potassium in heart contraction, explain why this specific wave of an ECG is affected?
