Abstract:
Objective To investigate the relationship between day and night regularity of asymptomatic ventricular presystole (VPS) and the activity of autonomic nervous system and its clinical significance Methods Thirty children with the absence of underlying organic heart disease were examined with 24 hour dynamic electrocardiogram (DCG), the function of autonomic nervous system and ventricular late potentials (VLP) Results The rate (43%, 13/30) was the day type VPS, 12 out of the 13 resulted from increased activity of sympathetic nerve The rate (30%, 10/30) was the night type VPS, all of them resulted from the activity of the vagus nerve enhanced There was a positive correlation between VPS frequency of day type and heart rate ( r =0 67, P
