[Arrhythmia in children with dilated cardiomyopathy (data of 24-hour ECG monitoring)].

The authors demonstrate potentialities of long-term ECG monitoring in the diagnosis of heart rhythm and conduction disturbances in children with dilated cardiomyopathy. Provide the results of comparative studies of routine and 24-hour ECG monitoring in children with dilated cardiomyopathy under every-day life conditions. Show that during 24-hour ECG monitoring, all the children with the above pathology manifest heart rhythm and conduction disturbances of varying intensity and prognostic significance.

[Morphofunctional state of the heart in dilated cardiomyopathy in children].

To study the morphofunctional state of the heart, 49 children aged 1 to 15 years with dilated cardiomyopathy (DCMP) were examined. The diagnosis was established on the basis of comprehensive clinical and instrumental examinations. It was discovered as a result of echocardiography that children with dilated cardiomyopathy show considerable dilatation of the cardiac chambers, accompanied by moderate hypertrophy of the myocardium (mainly of the left ventricle) and by appreciable impairment of the function of myocardial contraction and relaxation together with derangement of heart pump function.
