A total of 41 postoperative patients with CHD (22 Fontan, 19 TOF) and 34 age-matched healthy controls underwent 24-h electrocardiogram recordings during sleep.

Patients who underwent TOF repairs exhibited significantly lower low frequency, high frequency, standard deviation of all normal R-R intervals, and the root mean square of successive differences between R-R intervals values than those in the control group. Nonlinear indices, particularly HFD, were unaffected by heart rate, enhancing reliability in pediatric populations. Age-related declines in fractal indices in postoperative patients with TOF repairs suggest progressive autonomic dysfunction. Nonlinear HRV analysis offers valuable insights into autonomic dysregulation in postoperative patients with CHD, surpassing conventional methods in reliability.
