Which scenario is a contraindication to exercise for someone with arrhythmias?

• A. Uncontrolled ventricular arrhythmias.
• B. Well-controlled atrial fibrillation with normal rate.
• C. Normal heart rhythm during exertion.
• D. Regular, supervised exercise program.

Answer: (A)

The key idea is safety during exercise for people with heart rhythm problems. Uncontrolled ventricular arrhythmias are a major red flag because exertion increases sympathetic drive, heart rate, and myocardial stress, which can provoke dangerous rhythms and compromise blood flow. In this state, exercising can precipitate life-threatening events, so it’s contraindicated until a clinician can stabilize the rhythm and confirm it’s safe to resume activity. In contrast, well-controlled atrial fibrillation with a normal rate is not an automatic barrier to exercise—if the rhythm and rate are managed and there are no other safety concerns, many people benefit from activity. A normal rhythm during exertion indicates the heart handles exercise without arrhythmias being triggered. Regular, supervised exercise is also appropriate once a patient has clearance, as it supports cardiovascular health and rhythm management.
