Ex testing and stress testing

Question 1

why perform a stress test?

Answer 1

• evaluate cardiopulm symptoms: chest pain, pressure, SOB/DOE, fatigue
• determine disease severity/prognosis
• evaluate effects of surgical/mediccal interventions
• determine dysrhytmia presence/management
• determien functional capacity; screen for exercise partipcation/prescritipn/return to work

goal=ilicit symptom

Question 2

what is a peak exercise test?

Answer 2

the symptom is limited (e.g. fatigue/SOB/DOE)

Question 3

what is a max exercise test?

Answer 3

specific conditions must be met

for ex: ECG changes (ST segment elevation/depression); angina, “criteria for max”

Question 4

give some examples of submax tests

Answer 4

5xSTS
6 MWT, shuttle walk test, step tests, cycle tests
TUG, BERG

Question 5

what is the criteria for Vo2 max?

Answer 5

HR; BP plateau with increasing workload

• within 5-15 beats of predicted HR max
• RER > 1.15
• blood lactate> 8-10

Question 6

what is it called when the criteria for Vo2 max is not achieved?

Answer 6

Vo2 peak

Question 7

when should you stop an exercise test?

Answer 7

-inability to monitor patient
-patient request; fatigue/DOE
-angina
-abnormal ECG:
VT/VF; 2nd/3rd heart blocks; rapid AF/flutter
repolarization abnormalities consistent with ischemia :T wave inversion…S-T segment elevation/depression

-abnormal hemodynamnic responses:
decrease SBP>10 with increase workload
HTN: resting BP>210/110
SBP should never go down
exercising SBP>250 and DBP>115

-HR responses
if > 75%

-pulm responses: SpO2 <88

-excessive DOE or other symptoms
RPE >17 or 7

• dizziness/pallor
• confusion/balance changes
