Which statement about ectopic beats in aging is correct?

• A. Ectopic beats become more common and symptomatic
• B. Ectopic beats become more common but usually asymptomatic
• C. Ectopic beats become rare
• D. Ectopic beats always require surgery

Answer: (B)

Ectopic beats are premature contractions that originate outside the heart’s normal pacing pathway. As people age, the heart undergoes structural and electrical changes—such as mild fibrosis, gradual conduction tissue alterations, and possible atrial enlargement—that make ectopic activity more likely. Yet in most older adults, these extra beats do not cause symptoms; they’re often found incidentally on an ECG or during monitoring. That combination—increased frequency with age but typically no symptoms—explains why the statement that ectopic beats become more common but are usually asymptomatic is the best description. If ectopy is frequent or there’s underlying heart disease, symptoms can occur or more serious rhythms may develop, but this doesn't make ectopic beats inherently problematic for the typical aging individual.
