“…At 2 weeks of age, infants with TGA had lower baseline HF HRV values and a lower magnitude of recovery when compared with infants born healthy. These findings are consistent with previous findings that infants and children with congenital heart disease are more likely to have impaired autonomic function when compared with their healthy peers (Butera et al, ; Davos et al, ; Heragu & Scott, ), likely due to their early experience in an intensive care unit setting and recovery from a major surgical intervention (Kaltman et al, ; Ushiyama et al, ). By 2 months of age, however, there were no significant group differences in any of the HF HRV measures.…”

“…Myelinated vagal pathways are still developing, and the ICU environment likely stimulates primarily defensive responses, that is, sympathetic activation, and, at times of overwhelming distress, sympathetic immobilization, as evidenced by apnea and bradycardia. Altered HF HRV in infants and children with congenital heart disease, documented in several studies (Aletti et al, ; Butera et al, ; Kaltman et al, ), may in turn affect infants' regulatory and social engagement skills (Porges, ).…”

The quality of maternal-infant interaction is a critical factor in the development of infants' autonomic function and social engagement skills. In this secondary data analysis, relationships among infant and maternal affect and behavior and quality of dyadic interaction, as measured by the Parent-Child Early Relational Assessment, and infant autonomic function, as measured by heart rate variability, were examined during feeding at 2 weeks and 2 months of age in 16 healthy infants and in 15 infants with transposition of the great arteries (TGA). Contrary to previous research, at 2 weeks infant age, mothers of infants with TGA had significantly higher scores in affect and behavior than did mothers of healthy infants. The affect and behavior and quality of dyadic interaction of infants with TGA also did not differ from that of healthy infants. Although infants' social engagement skills did not differ by health condition (TGA or healthy), these skills did differ by parasympathetic nervous system function: infants better able to suppress vagal activity with challenge had more positive and less dysregulated affect and behavior, regardless of health status. These findings suggest that maternal-infant interactions for some cardiac disease subgroups may not differ from healthy dyads. Additional research is required to identify both healthy and ill infants with delayed autonomic maturation and to develop and test interventions to enhance critical interactive functions.

“…Thus, vagal HR control seems to be mildly reduced, corresponding to previous findings (2, 4–6). However, the values reported here are generally less abnormal than those reported in prior studies, even though the degree of pulmonary regurgitation and right ventricular dilatation in our group was similar to that reported by Davos (4).…”

Arrhythmias in patients with repaired tetralogy of Fallot (ToF) might be due in part to altered autonomic heart rate (HR) control caused by altered right ventricle hemodynamics. This study investigated autonomic HR control in ToF adolescents at rest and during unloading of the right ventricle. A total of 17 ToF patients and 56 healthy controls aged 12 to 18 years underwent orthostatic stress with lower body negative pressure (LBNP) of −20 mm Hg. HR, blood pressure and stroke volume were recorded non-invasively. Indices of HR variability were computed in time and frequency domains. All ToF patients also underwent cardiac magnetic resonance imaging, demonstrating pulmonary regurgitation and right ventricular dilation. At rest, HR variability indices of vagal heart rate control were non-significantly lower in the ToF patients compared to controls. During LBNP, HR increased more in controls than ToF patients (p ≤ 0.001). Further, most HR variability indices decreased among controls, but increased among ToF patients (p ≤ 0.01 or p ≤ 0.001 for all variables), suggesting vagal activation in the ToF patients. In conclusion, adolescents after ToF repair have fairly normal HR control at rest despite altered right ventricular hemodynamics. During unloading of the right ventricle, however, vagal HR control increases in the ToF patients and decreases in the controls.

“…Однако, учиты-вая то, что в основе этих симптомов могут лежать такие серьезные заболевания как аномалии коронар-ных артерий, болезнь Кавасаки, перикардиты, мио-кардиты и др., в каждом случае возникновения у больных жалоб на боли в сердце, необходимо исключение кардиальной патологии на основании Наибольшее редуцирование ВРС в этой группе отмечается, как правило, среди больных с тетрадой Фалло [500]. Снижение SDNN, триангулярного индекса и отношения средней дневной к средней ночной ЧСС (циркадный индекс) показали себя как предикторы плохого прогноза (в том числе ВСС) у детей с ДКМП [47,501,502], АВ блокадой 3 степени [503].…”

Patients Operated for Tetralogy of Fallot and with Non-Sustained Ventricular Tachycardia Have Reduced Heart Rate Variability

Abstract: ToF patients, particularly those with ventricular arrhythmias, have significant impairment of sympatho-vagal balance, characterized by a reduction of vagal drive.
