High risk @ moderate & vigorous intensity: what/who is needed - ANSWER medical
exam, exercise test & MD supervision prior to exercise
Moderate risk @ vigorous intensity: what/who is needed - ANSWER only medical
exam prior to exercise
Low risk @ moderate & vigorous intensity: what/who is needed - ANSWER nothing
Moderate risk @ moderate intensity: what/who is needed - ANSWER nothing
Which patients (risk stratified) can be supervised by non-physician health care professionals
if professionals are specifically trained in CET & physician is readily/immediately available? -
ANSWER all risk groups can be; low risk can be supervised w/o physician immediately
available
Who should have PFT's done? - ANSWER all smokers <45y.o & anyone presenting with
dyspnea
ECG monitoring during test - ANSWER recorded last 15secs of each stage
BP monitoring during test - ANSWER measured/recorded last 45secs of each stage
HR monitoring during test - ANSWER recorded last 5secs of each stage
1
, ECG monitoring after test - ANSWER monitored continuously, recorded immediately
post exercise, during last 15secs of 1st minute then every 2 minutes thereafter
BP monitoring after test - ANSWER measured & recorded immediately post exercise
then every 2 minutes thereafter
HR monitoring after test - ANSWER monitored continuously then recorded during last
5secs of each minute
Technetium (tc) -99m - ANSWER comparison of rest & stress imaging permits ID of
fixed & reversible perfusion abnormalities as well as differentiation; permits higher does
with less radiation exposure; preferred imaging agent
Thallum 201 - ANSWER circulates myocardium showing images of where
lack/inadequate blood flow is; shows images of inadequate perfusion
Dobutamine - ANSWER elicits wall motion abnormalities by increasing HR & therefore
myocardial O2 demand; infused intravenously with dose increased gradually until maximal
does or endpoint is acheived
Adenosine (dipyridamole) - ANSWER causes maximal coronary vasodilation in normal
epicardial arteries; rest images then compared with imaging obtain after coronary
vasodilation
Optimal exrx - ANSWER cardiorespiratory fitness (CRF), muscular strength, muscular
endurance, flexibility, body comp, & neuromotor fitness (gradual progression of
volume/intensity)
Overload principle - ANSWER states exercise below minimum intensity will not
challenge body sufficiently to result in changes in physiologic parameters
