Textbook Question
Chapter 19, Problem 1CAL
A young man was doing some vigorous exercise when suddenly he felt chest pains just before he passed out. Upon being revived, he was taken to the hospital for examination. The medical personnel ran standard tests and ECG tracings, then said it would fine for him to resume his normal activities and workouts.
1. Why might the increase in heart rate associated with a vigorous exercise program be the cause of his becoming unconscious?
- a. increase in blood pressure throughout the body
- b. failure of the conduction system
- c. increase in return volume of blood to the heart
- d. coronary blood flow reduction due to tachycardia

A. Blood doping and EPO use are illegal acts banned from sports events. What are the specific health risks of such behavior – explain briefly based on what you learned about blood components in the body.
B: A heart murmur was detected in a teenage girl who sought medical care due to feelings of chronic fatigue. Her radial pulse was rapid and weak. An echocardiogram and coronary angiography revealed that she had a ventricular septal defect and mitral stenosis (roughening or constriction of the walls surrounding the mitral valve). Predict her ECG pattern and explain her symptoms. Would you be concerned if you find that her plasma cholesterol concentration is also high? Why?
