| General principles for exercise testing (7) |
|
Definition
do not test if any doubt/questions and no physician available
select test suited to individual
start at low intensity, gradually progress
S/Sx monitored regularly
watch for test termination red flags (ECG or BP abnormalities)
min of 5 min recovery (high risk time for arrhythmia)
room temp <22ºC, <60% humidity |
