Noninvasive methods of diagnosis of electrical instability of the myocardium in children

One of the urgent problems of modern pediatrics is the prediction of the development of electrical instability of the myocardium. The article reflects the risk factors, the pathogenetic mechanism of arrhythmias. The use of available non-invasive methods allows timely diagnosis of electrical heart instability in children. The parameters of the electrocardiogram are described, which reflect the processes of depolarization and repolarization of the ventricular myocardium, which make it possible to identify patients at risk for the development of life-threatening cardiac arrhythmias.
