DETAILED ANSWERS (VERIFIED
ANSWERS) |ALREADY GRADED A+
Ergometer - Answers - ✔✔ an apparatus that measures work or energy expended
during a period of physical exercise.
Treadmill - Answers - ✔✔ - Speeds ranging from 1 - 8 mph
- Incline ranging from 0%-20%
Indicatations of cardiovascular disease - Answers - ✔✔ -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 - Answers - ✔✔ -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 - Answers - ✔✔ -used for pts with orthopedic, vascular, or
neurological limitations
-need the ability to be adjusted manually or electronically
most; least - Answers - ✔✔ -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 - Answers - ✔✔ -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 - Answers - ✔✔ -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 - Answers - ✔✔ -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 - Answers - ✔✔ -inability to exercise due
to orthopedic, neurological, circulator or respiratory conditions
-general debilitation
-presence of calcium channel blockers
Data for stress results - Answers - ✔✔ -ECG results
-HR & BP response
-presence or absence of CV symptoms
-aerobic exercise capacity
-presence of symptoms
-percent of pt's max HR
MET - Metabolic Equivalent - Answers - ✔✔ -a measure of exercise intensity based on
oxygen consumption
-1 is = the amount of o2 a person consumes per unit of body weight during 1 min of rest
Non-coronary causes of ST depression - Answers - ✔✔ -severe HTN
-severe aortic stenosis
-cardiomyopathy
-anemia
-hypokalemia
-severe hypoxia
-digitalis
-sudden excessive exercise
-left ventricular hypertrophy
-mitral valve prolapse
-pre-excitation syndrome: WPW
-aortic or mitral regurg (volume overload)
-supraventricular tachyarrhythmias
V5 - Answers - ✔✔ Lead that detects myocardial ischemia
Persantine Chemical Stress Test - Answers - ✔✔ -aka dipyridamole
-anti-platelet agent that dilates the coronary blood vessels
-side effects: abd upset, arrhythmias, dizziness, headache, CP, low BP, rarely a heart
attack or stroke
-aminophylline reverses the side effects
