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 benign ectopic atrial beats that can occur in healthy people, not just those with heart disease. They are commonly seen across a wide age range, including very young and very old individuals, and are also frequent in athletes who often have higher vagal tone and increased atrial ectopy. Because they can appear in people without cardiac disease and aren’t limited to a specific non-disease group or to sleep, the groups described as very old, very young, or athletes best capture where PACs are commonly seen.
