Neurologic complications of brady-arrhythmias

Predictive significance of the life history of children with gastroesophageal reflux for predicting the development of arrhythmias and conduction disorders

The aim: to improve the early diagnosis of cardiac arrhythmias and conduction disorders in children with gastroesophageal reflux, by studying the prognostic significance of the life history in this group of patients. Materials and methods. 56 children aged 8 to 18 years, mean age 14,93±2,62 years were examined. All examined children were divided into two alternative groups: Group I (main) was represented by 28 children with gastroesophageal reflux in combination with cardiac arrhythmias and conduction disorders, and Group II (control) - 28 children with only gastroesophageal reflux without cardiac arrhythmias and conduction disorders. Patients underwent clinical, anamnestic (with a detailed study of life history) and instrumental studies (electrocardiography, Holter daily ECG monitoring, esophagogastroduodenoscopy). Results. When analyzing the prognostic significance of the patient's life history, it was found that its very high level was observed for the number of foci of chronic infection (I=6.0) and the frequent incidence of a child up to year old of life (I=3.05). High prognostic value was registered relative to the number of diseases suffered by the child per year on average (I=2.35), and moderate predictor properties are characteristic of chickenpox (I=0.89) and the number of chronic diseases at present (I=0.71). The duration of breastfeeding showed low (I=0.30) prognostic significance. Suffered previously bacterial infections did not have predictor properties (I=0.12). In general, the prognostic significance of the patient's life history was high (I̅=2.20). Conclusions. It was found that in general the prognostic significance of the patient's life history was high (I̅=2.20) It is determined that in favour of the development of cardiac arrhythmias and conduction disorders evidence: the number of foci of chronic infection ≥1-2; lack of frequent morbidity in a child up to a year of life; the number of diseases suffered per year ≤5; the presence in past medical history of chickenpox; the number of chronic diseases in a child at present ≤2 and short-term (≤9 months) breastfeeding. It has been established what denies probability of development of the researched pathology: absence of the centers of a chronic infection; the presence frequent incidence of a child up to year old of life; the number of diseases suffered per year≥6, and chronic diseases at present ≥3; longer (≥9 months) breastfeeding and no history of chickenpox
