Abstract: Objective To explore the function of autonomic nerves system in children with congenital heart disease (CHD) combined with paroxysmal supraventricular tachycardia (PSVT). Methods Fifty children having PSVT and no CHD (PSVT group), 30 children with both PSVT and CHD (CHD group), and 50 cases of healthy children (control group) were selected. The difference of 24-hour heart rate variability (HRV) among three groups was analyzed retrospectively. Results There were statistical differences in the long-range time domain HRV indexes, including SDNN, SDANN, SDNN Index, pNN 50 , and RMSSD among three groups (F=80.32-?263.18, P all??0.05). The SDNN, SDANN, SDNN Index, pNN50, and RMSSD were signiifcantly decreased in CHD group compared with PSVT group (P all?
