Response to “Exercise-induced ectopy and its relationship to fitness, cardiac function, and markers of severity in youth with pectus excavatum”

We read with great interest the article entitled “Exercise-induced ectopy and its relationship to fitness, cardiac function, and markers of severity in youth with pectus excavatum” by Piczer et al. [1]. The authors provide an important contribution by demonstrating that patients with pectus excavatum exhibit a higher incidence of ventricular ectopy, and that this finding is more common in individuals with greater markers of chest wall structural abnormality. This observation adds to our understanding of the potential cardiovascular implications of pectus excavatum beyond its well-recognized cosmetic and psychosocial impact.

In brief

This correspondence discusses findings linking pectus excavatum severity to increased ventricular ectopy during exercise in youth. The commentary highlights the cardiovascular implications of chest wall deformities beyond cosmetic concerns, emphasizing the relationship between structural abnormality and cardiac arrhythmias.

Pectus excavatum patients show higher incidence of ventricular ectopy during exercise compared to controls.
Ventricular ectopy frequency correlates with severity of chest wall structural deformity in pectus excavatum.
Pectus excavatum has cardiovascular implications beyond cosmetic and psychosocial effects.
Exercise testing may reveal cardiac rhythm abnormalities in youth with pectus excavatum.
