Integrated model for the risk assessment of the unfavourable course of binodal pathology in children

Abstract

The article presents a model the risk assessment of the unfavorable course of binodal pathology in children. We enrolled 177 consecutive patients with binodal pathology. In the analysis of complaints, clinical picture and data of electrocardiographic and electrophysiological parameters, factors that influenced the course of the binodal pathology were established. Risk factors were: male gender, the age of manifestation of the disease over 14.5 years, the minimum heart rate is less than 52 beats per minute (before the medication), the value of SNRT more than 1510 ms (before the test with atropine), the minimum heart rate after the administration of atropine is less than 96 bpm. The total risk score is calculated as the sum of the values of these indicators (5 risk factors) and can take values from 0 to 5 points. Three levels of total risk score are singled out: 0 points — low probability of negative dynamics; 1–3 points — an insignificant probability of negative dynamics; 4–5 points — significant risk of negative dynamics.
