Congenital heart disease is the most common congenital defect. During childhood, survival
is generally good but, in adulthood, late complications are not uncommon. Abnormal …

Abstract Purpose Patients with Fontan circulation have reduced heart rate variability (HRV)
in supine position. However, neither cardiac autonomic nervous activity (CANA) in response …

Background: Surgical repair of congenital heart diseases (CHD) affects heart rate variability
(HRV) in different ways. It leads to varying degrees of cardiac autonomic derangement …

This study aims to investigate how di൵erent types of regular physical activity a൵ect cardiac
functions in school children. This is a cross-sectional review of 15 children who are not …

Arrhythmia is related to heart rate variability (HRV), which reflects the autonomic nervous
regulation of the heart. We hypothesized that autonomic nervous ganglia, located at the …

Background: This study aims to investigate how different types of regular physical activity
affect cardiac functions in school children. Methods: This is a cross-sectional review of 15 …

Background: Fontan surgery is performed in children with univentricular heart defects.
Arrhythmias are frequent complications, occasionally requiring pacemaker treatment …

Chronic changes in cardiac autonomic control to compensate for hemodynamic alterations
due to CHD or due to surgical intervention may play a role. Thus, assessment of cardiac …

Heart failure is the main cause of death in children with congenital heart disease (CHD) with
long term consequences, such as impaired linear growth and worse neurodevelopmental …
