Exercise Testing

Question 1

what is mean arterial pressure?

Answer 1

(SBP+DBP)/2

Question 2

how should exercise impact SBP and DBP?

Answer 2

SBP should increase with exercises
DBP should stay the same (should not change by more than 10 mmHg)

Question 3

what is the function of a B-blocker?

Answer 3

block epinephrine and norepinephrine from binding to their receptors resulting in decreased HR

Question 4

what is an exercise tolerance test (ETT) used for?

Answer 4

measures exercise capacity and physiological responses
determines functional aerobic capacity and whether ischemia is present

Question 5

what does a positive ETT indicate?

Answer 5

myocardial oxygen supply is inadequate to meet myocardial oxygen demand
+ for ishemia

Question 6

how does the UE ergometer impact HR, SBP, SV, and RPP?

Answer 6

increases HR and SBP
decreases SV
increases RPP

Question 7

how does the LE exercise impact HR, SBP, SV, and RPP?

Answer 7

decreases HR and SBP
increases SV
decreases RPP
