AVNRT affects most commonly which population?

• A. Males 40-50
• B. Females 20-30
• C. Children under 10
• D. Elderly over 70

Answer: (B)

AVNRT is the most common form of paroxysmal SVT and shows a clear female predominance, with most cases starting in young adulthood. The typical patient is a woman in her 20s to 30s. This age-and-sex pattern reflects how AV nodal dual-pathway physiology tends to manifest clinically in this group. While AVNRT can occur outside this range, the combination of being female and in the 20s–30s is the most frequently observed presentation, making that population the best answer.
