Resting bradycardia requiring clearance prior to exercise is best described by which statement?

• A. Resting tachycardia with no symptoms.
• B. Resting bradycardia with symptoms or conduction abnormality.
• C. Normal resting heart rate.
• D. Mild wheeze.

Answer: (B)

Resting bradycardia requiring clearance before exercise is when the heart rate is slow at rest but this is accompanied by symptoms or a conduction abnormality. Slow resting heart rate can be normal in athletes due to higher vagal tone, but if the person experiences symptoms such as dizziness, fainting, chest discomfort, or unusual fatigue, or if there’s evidence of a conduction problem on ECG (like a block or sinus node dysfunction), medical clearance is warranted before engaging in exercise. The other statements don’t fit because a resting tachycardia with no symptoms is not about bradycardia needing clearance, a normal resting heart rate isn’t describing bradycardia, and a mild wheeze relates to the lungs rather than heart rhythm.
