ACSM-EP Clinical Exercise Testing 3

Question 1

When performing a 6-minute walk test (6MWT) in a patient with heart failure, which outcome measure is most clinically relevant?

Accepted Answer

Total distance walked in 6 minutes

Answer

Total distance walked in 6 minutes is the primary outcome of the 6MWT and correlates with functional capacity and prognosis in heart failure patients.

Question 2

Which ECG finding during exercise most specifically indicates left ventricular volume overload rather than ischemia?

Accepted Answer

Tall R waves with ST elevation in aVR

Answer

ST elevation in aVR with reciprocal changes can indicate left main or proximal LAD occlusion causing volume/pressure overload, though interpretation requires full clinical context.

Question 3

A clinically obese patient (BMI 41) cannot complete Stage 1 of the Bruce protocol. What is the most appropriate alternative protocol?

Accepted Answer

Modified Bruce protocol starting at a lower grade

Answer

The Modified Bruce protocol adds two lower-intensity stages (0% and 5% grade at 1.7 mph) before Stage 1, making it appropriate for deconditioned or obese individuals.

Question 4

During a maximal exercise test, a patient's RER reaches 1.15. What does this indicate?

Accepted Answer

Maximal or near-maximal effort has been achieved

Answer

An RER >1.10 during exercise indicates significant CO2 release from bicarbonate buffering of lactic acid, confirming near-maximal effort.

Question 5

Which blood pressure response during exercise is considered hypertensive and warrants test termination?

Accepted Answer

SBP >250 mmHg or DBP >115 mmHg

Answer

ACSM guidelines recommend stopping the exercise test if SBP exceeds 250 mmHg or DBP exceeds 115 mmHg to prevent hypertensive emergency.
