Ergometer correct answer: an apparatus that measures work or
energy expended during a period of physical exercise.
Treadmill correct answer: – Speeds ranging from 1 – 8 mph
- Incline ranging from 0%-20%
Indicatations of cardiovascular disease correct answer: –
Changes in the J-point & ST segment
-Mets < 6.5 -Duration < 6 minutes -Low peak HR -Maintaining a low systolic BP -Severe ST depression -Prolonged ST depression Cardiolite correct answer: -AKA radioactive technetium -assesses the volume of blood pumped with each heartbeat -labels the red blood cells -ability to count the number of red blood cells that pass through each chamber over several heartbeats -side effects: swelling of face & tongue, hives, itching, headache, CP, and nausea Bicycle Erogmeter correct answer: -used for pts with orthopedic, vascular, or neurological limitations -need the ability to be adjusted manually or electronically 1 / 2 most; least correct answer: -Upsloping ST that does not return to baseline in 80 milliseconds beyond the J-point: severe -Downsloping ST: _ severe & 99% dependable for
predicting CAD
Dobutamine Stress Test correct answer: -adrenergic agonist
-stimulates the beta-1 receptors in the cardiovascular system
-increases BP & HR which increases the workload
-may lead to arrhythmias, SOB, headache, low BP, CP, or
tremors
-Beta-blockers can reverse the side effects
normal test findings correct answer: -J point that is slightly
depressed, sloping up into an ST segment that returns to baseline
within 80 milliseconds (.08) from the J-point
Indicates myocardial ischemia correct answer: -upsloping ST
which doesn’t return to baseline within 80 milliseconds (.08)
-J point depression followed by a horizontal ST segment below
baseline
-downward sloping ST segment
-J point & ST elevation
Indications for a pharmacological stress test correct answer: –
inability to exercise due to orthopedic, neurological, circulator
or respiratory conditions
-general debilitation
-presence of calcium channel blockers
Data for stress results correct answer: -ECG results
