Exercise Tolerance Testing Flashcards
What is and Exercise Tolerance Test (ETT)/Graded Exercise Test used to determine?
Determination of functional exercise capacity
On an ETT, what is this used to detect?
Presence of Ischemia
What phase of cardiac rehab is a Symptoms Limited ETT administered.
Prior to Phase II outpatient Cardiac Rehab
Utilizing a Maximal ETT can only be completed with what type of life support training on standby?
Advanced Cardiac Life Support
What percentage of age predicted HR max is a submaximal ETT terminated at?
85% of age predicted HRmax
What conditions is a Submax ETT used for?
Evaluate early recovery for:
- After MI
- Coronary Bypass
- Coronary Angioplasty
What type of ETT allows a patient to reach steady state with increasing intensities?
Step Test
What type of ETT does not allow a patient to reach steady state with increasing intensities?
Ramp Test
When an ETT is positive what does this indicate?
Positive for Ischemia
- myocardial O2 supply is inadequate to meet demand
When an ETT is negative what does this indicate?
At every workload.
- Balanced O2 supply and demand
List of symptoms suggesting exercise intolerance: READ
- Persistent Dyspnea
- Dizziness or Confusion
- Anginal Pain
- Severe Leg Claudication
- Excessive Fatigue
- Pallor, cold sweat
- Ataxia, incoordination
- Pulmonary Rales
What is pulse oximetry used for?
Measure arterial O2 saturation
When does HR and Oxygen uptake plateau?
Just before Maximal oxygen uptake (VO2 max)
On and EKG what is indicative of myocardial ischemia?
ST segment depression > 1 mm
What is the amount of O2 consumption at rest?
3.5 mL/kg minute
