Exercise Testing Flashcards
reasons to use exercise testing?
diagnostic- symps limit end point
functional- stop at 4-6 mets or at 75% APMHR
theraputic- endpt. varies
Bruce and Balke are what kind of tests?
max protocol tests
Incremental max test?
Bruce
steady state max test?
Balke
what scales should u use with patients while doing exercise testing?
angina scale (1-4) dyspnea scale (1-4)
what is a functional capacity (in METS) that is an indicator of an adverse prognosis?
functional capacity < 5 METS
How do they use a PET to test exercise/stress tolerance?
PET uses a radioactive tracer to monitory coronary blood flow at rest, then they give u dipyridamole (an anticoagulant) to “stress” your heart and they watch the blood flow for any signs of stenosis
What is a SPECT test?
single photon emission computed tomography
uses gamma rays to detect myocardial blood flow. give the pt the radioactive stuff at the peak of the stress test then 4 hours later at rest.
in a SPECT test how can u tell if it is an MI or just ischemia?
if the cold spot stays cold during rest= MI (dead spot) if the cold spot goes away with rest= ischemia that just couldn’t keep up during exercise.
