CARDIAC REHABILITATION-EXERCISE PHYSIOLOGY

SUMMARY

1. Total O₂ consumption (VO₂): represents the total O₂ consumption of the whole body, corresponds more to skeletal muscles.

2. Aerobic capacity (VO₂ max): O₂ consumption during maximal exercise. Reaches a plateau despite further increases in workload. Provides a reliable & reproducible measure of dynamic work capacity. Done with treadmill or leg-cycle ergometer testing. Important in prognostication.

3. Myocardial O₂ consumption: measured with cardiac catheterization.

4. Double product (RPP): refers to the work required of the heart, RPP = SBP * HR.

5. Metabolic equivalent (MET): ratio of working metabolic rate to resting (basal) metabolic rate. 1 MET = basal metabolic rate.
