Which of the following is MOST unlikely to alter resting and exercise heart rate?
  1. Pregnancy
  2. Osteoporosis
  3. Pacemaker
  4. Smoker with 2 pack per day habit
Explanation
Answer: B - While many diseases will alter both resting and exercise heart rates, osteoporosis is not one of them. Patients with cardiopulmonary disease, especially those with a pacemaker implant or those on beta blocker medications, can show dramatic alterations in their heart rate patterns. Smokers, especially heavy smokers, will notice a change in heart rate immediately (from the immediate effects of nicotine) and over time (because of the changes to the cardiorespiratory system caused by smoking).
