Linear QT correction may refine pediatric exercise ECG interpretation; leaves open effects on clinical decisions or outcomes.
How does the QT interval change in relation to heart rate during exercise and recovery in healthy children?
The relationship between QT and heart rate is linear and differs during exercise and recovery in children, suggesting linear correction is superior to Bazett's method for exercise testing.
Viitasalo et al. (1996) studied this question.
