Tachyarrhythmias with uncontrolled ventricular rates during or around exercise testing are considered which type of contraindication?

• A. No contraindication
• B. Absolute contraindication
• C. Relative contraindication
• D. Optional contraindication

Answer: (C)

Classifying tachyarrhythmias with an uncontrolled ventricular rate during or around exercise testing as a relative contraindication reflects weighing risk against benefit. An uncontrolled ventricular rate during exertion can worsen hemodynamics, trigger syncope, or progress to more dangerous rhythms, so the test isn’t routinely allowed. Yet it isn’t an absolute ban because if the rhythm can be controlled, the patient is stable, and the test is performed with close monitoring and immediate ability to stop and treat if needed, it may be considered. This balance of risk and controlled conditions is why the situation is labeled as a relative contraindication.
