CHANGES OF HEART RHYTHM IN PEDIATRIC PATIENTS WITH SEVERE TRAUMATIC BRAIN INJURY
Objective: to study the effect of severe TBI (traumatic brain injury) on the heart rhythm and age-related features of changes in circadian rhythms of the heart rate, depending on the severity of the patients’ condition.Materials and Methods: results of analysis of cardiac circadian rhythm (mean daily value, acrophase, batiphase) of 90 patients with severe TBI were studied. Patients were divided into three groups and further into subgroups depending on the severity of their condition.Results: protection of cardiac function was insufficient and inconsistent which resulted in shifts of acrophase and batiphase while patients were in the ICU. Despite the timely interventions, routine management plan in the ICU could not fully provide the protection of circadian rhythm of sinus node. This allows to claim that the possibilities of optimizing of management plan of this category of patients are not depleted.
