Which age group is typically most affected by supraventricular tachycardia?

Supraventricular tachycardia (SVT) is most frequently seen in young adults to middle-aged individuals due to the physiological characteristics and health factors typical of this age group. In young adulthood, the heart is often more responsive to stressors and factors such as caffeine, stimulants, or atrial enlargement, which can trigger episodes of SVT.

Additionally, the prevalence of underlying structural heart issues or chronic diseases that may predispose individuals to arrhythmias tends to increase with age. As such, while SVT can occur across various ages, the young adult to middle-aged demographic tends to exhibit higher incidence rates. This makes them particularly notable for both the symptomatic presentation of SVT and potential recurrent episodes during this period of life.

In contrast, other age groups experience either distinct types of arrhythmias or different underlying triggers. Children and infants may experience SVT, but it often occurs due to congenital heart defects or specific health issues rather than the typical factors seen in adults. Meanwhile, older adults might have a variety of heart conditions that present differently, often resulting in a lower incidence of SVT compared to younger cohorts.
