Cardiac Rehab/HR Formulas; Karvonen Flashcards
How to Calculate Age Predicted HR Max?
220 - Age
When to use Karvonen Formula?
- Resting HR is known
- A range of HR max is asked for
How to Calculate using the Karvonen Formula?
(Heart Rate Reserve x % of Intensity) + Resting HR
How to Calculate Heart Rate Reserve?
HRmax - HRrest
What is an appropriate initial exercise prescription for an asymptomatic individual coming in for general deconditioning?
60-80% of HRmax
What setting is Phase I of Cardiac Rehab in? What must precede the initiation of this phase?
Inpatient; initiated after 24 hours of being stable
Can resistance training be utilized in stage I of cardiac Rehab?
NO!
FITT Principle for Phase I of Cardiac Rehab? Frequency
F: Short Session; 2 - 3 times a day
FITT Principle for Phase I of Cardiac Rehab? Intensity?
50-70% HRmax
FITT Principle for Phase I of Cardiac Rehab? Time/Duration
10-15 minutes
FITT Principle for Phase I of Cardiac Rehab? Type/Mode
- ADLs
- Supervised Ambulation
What setting is Phase II of Cardiac Rehab in? Typical Duration Passed Prior to Starting?
Outpatient; 4-6 weeks after MI
FITT Principle for Phase II of Cardiac Rehab? Frequency
2-3 Sessions/Week
FITT Principle for Phase II of Cardiac Rehab? Intensity
70 - 85% of peak (HRmax)
FITT Principle for Phase II of Cardiac Rehab? Time/Duration
30-60 minutes with 5-10 minutes of warm up and cool down
FITT Principle for Phase II of Cardiac Rehab? Type/Mode
Single mode of training (walking)
or
Multiple modes (treadmill, cycle, ergometer)
What can be implemented for Phase III of Cardiac Rehab?
Begin the implementation of strength/resistance training
Best place to start resistance training in Phase III? Progression
- Elastic bands and light hand weight (1-3 lbs)
Progression :
- Moderate Loads
- 12-15 Reps
For initiation of Cardiac Rehab Stage II is the use of inclined treadmill recommended?
Initially no (early phase), addition of incline as a progression.
What is Phase IV of Cardiac Rehab?
Maintenance Period/Phase
Location where Phase IV is held?
- Community Center
- Clinical Facilities
- YMCA
A patient must be physiologically stable in what areas to participate in Exercise during Stage IV?
- Clinically Stable Angina
- Medically Controlled Arrhythmias
Progression during Stage IV? Intensity, Frequency, Duration.
- 50-85% of Functional Capacity
- 3-4/week
- 45 minutes or more per session
Exercise Tolerance Tests can be Either Submax or Maximal? When is a submaximal test used?
Evaluate early recovery of patients post:
- MI
- Coronary Bypass
- Coronary Angioplasty
What enzyme is diagnostic for MI?
Elevation of Creatine Kinase, secondary to myocardial damage
Minimum amount of METs needed to complete ADLs?
5 METs
With resistance training what should maneuver should be avoided?
Avoid utilizing Valsalva Maneuver
