Summary

Some physiological factors, such as physical activity, or pathological factors, such as sepsis or diabetes, are known to modulate the overall autonomic activity and the individual's intrinsic capacity to regulate their sympathetic and parasympathetic balance. These conditions can alter the physiological autonomic balance, sometimes with positive consequences on the FC-breathing control and blood pressure adjustment, depending on the individual's position and the status of blood volume, but sometimes with deleterious effects, such as poor regulation of sinus cardiac activity and respiration rate. Cardiovascular autonomic neuropathy is a major complication of type 1 diabetes. Several studies have described autonomic dysfunction in patients with type 1 diabetes, but these data are derived from cohorts of adults and adolescents or short ECG recordings at rest. Moreover, there are often confounding factors such as sedentary/physical activity, overweight, exposure to post-pubertal hormonal peaks, toxic drugs, or cardiac therapy. These factors don't greatly influence children's autonomic physiological maturation, whereas diabetes can sometimes exist for several years. In this population, the search for cardiac dysautonomia is entirely appropriate.

Detailed description

The objective of this study is to evaluate the indices of heart rate variability (from a 24-hour Holter and a cutaneous conductance) in children with type 1 diabetes compared with healthy controls matched to sex and age, and to determine whether the occurrence of cardiac dysautonomia is correlated with the duration of diabetes progression.
