Premature Atrial Complex is commonly seen in which groups?

• A. Very old, very young, or athletes
• B. Middle-aged office workers
• C. Only in patients with heart disease
• D. Only during sleep

Answer: (A)

Premature atrial complexes are early beats that originate from atrial tissue outside the SA node. They’re common in healthy people and are especially seen in the extremes of age and in athletes, likely due to autonomic tone shifts and atrial remodeling from training. They aren’t restricted to heart disease, and they don’t only occur during sleep—they can occur at rest or with activity. That combination of being common in very young, very old, and athletes makes this group the best fit.
