How do contraindications differ for symptom-limited versus maximal exercise testing?

How do contraindications differ for symptom-limited versus maximal exercise testing?

• A. They are completely different in every respect.
• B. Symptom-limited testing terminates based on patient preference.
• C. Maximal testing uses the same contraindications, but the test continues longer.
• D. Symptom-limited testing terminates early based on signs or symptoms, but the same contraindications apply.

Answer: (D)

The safety rules that prohibit pushing someone through an exercise test don’t change with how you decide to stop it. The same list of contraindications applies in both symptom-limited and maximal testing. What differs is the reason for stopping. In symptom-limited testing, you terminate early when the patient experiences signs or symptoms that indicate they can’t continue safely—things like chest pain, dizziness, severe shortness of breath, or extreme fatigue. If a contraindication is present, you would stop as well, but the key is that the decision to stop is driven by the patient’s symptoms. In maximal testing, you aim to push toward near-peak effort, but you still must respect the same safety constraints. The test ends when maximal effort criteria are reached or when clinical signs indicate it’s unsafe to continue. If a contraindication arises, the test must be halted immediately. Hence, the contraindications themselves are the same across both approaches; the difference is that one ends because the patient can’t or shouldn’t continue due to symptoms, while the other ends because the test has reached a planned maximal level or safety threshold.
