Answer to Question 1
G.P.'s cardiorespiratory responses (pulse, BP, respiratory gases oxygen and carbon dioxide, and
perceived exertion) to specific workloads will be evaluated to ensure that he can safely exercise in
the intensity range prescribed for him.
His resting (lowest) and peak (highest) exertional heart rates will be incorporated into the exercise
prescription.
The exercise prescription will start him at a workload that is not dangerous or emotionally
threatening to him (e.g., slow and easy).
Just as medications are prescribed (type, dose, time, route), exercise for cardiac patients should be
prescribed in these terms:
Type of exercise (what kind)
Intensity of exercise (how hard)usually as pulse or perceived exertion
Frequency of exercise (how often)usually beginning at 3 days per week
Duration of exercise (how long)usually measured in minutes or distance
What is the safest level of activity for G.P., and what problems could develop at what intensity?
Answer to Question 2
The manufacturer of the pacemaker should also provide information on the vulnerability of its
product. Information might vary with the different devices.
The American Heart Association is a good source of information and literature with the most recent
warnings and standards.
