What does MET stand for in exercise physiology?
Answer: Metabolic Equivalent of Task
MET stands for Metabolic Equivalent of Task and represents the ratio of metabolic rate during an activity to the resting metabolic rate, where 1 MET equals approximately 3.5 mL O2/kg/min.
The Karvonen formula is used to calculate which exercise parameter?
Answer: Target heart rate during exercise
The Karvonen formula calculates target heart rate using heart rate reserve (maximum HR minus resting HR) multiplied by the desired intensity percentage, then adding resting HR.
Which exercise modality forms the foundation of most cardiac rehabilitation programs?
Answer: Continuous aerobic exercise such as walking and cycling
Continuous aerobic exercise including walking, treadmill, and cycling is the cornerstone of cardiac rehabilitation due to its proven cardiovascular benefits and easily adjustable intensity.
How many supervised Phase II cardiac rehabilitation sessions does Medicare typically cover for eligible patients?
Answer: 36 sessions
Medicare covers up to 36 supervised Phase II cardiac rehabilitation sessions for eligible patients following qualifying cardiac events such as MI, CABG, or heart valve repair.
Which systolic blood pressure level during exercise should prompt IMMEDIATE termination?
Answer: Systolic BP exceeding 250 mmHg
A systolic blood pressure exceeding 250 mmHg during exercise represents a hypertensive crisis and requires immediate cessation to prevent cardiovascular complications including stroke.
Which medication class most commonly blunts the heart rate response during exercise, requiring modification of target heart rate calculations in cardiac rehabilitation?
Answer: Beta-blockers
Beta-blockers reduce chronotropic response by blocking adrenergic receptors, so exercise heart rate does not rise normally, requiring lower target HR ranges or RPE-based prescription instead.
What is the PRIMARY benefit of completing cardiac rehabilitation after coronary artery bypass graft surgery?
Answer: Improved exercise capacity and quality of life
Cardiac rehabilitation after CABG primarily improves exercise capacity, functional status, and quality of life, while also reducing risk factors and improving psychological outcomes.
