Comparative assessment of indicators of the morfo-functional state myocardium in children with ventricular premature beats and tachycardia of WPW-syndrome

The article presents information about the structural changes in the heart of children with ventricular premature beats end tachycardia of WPW-syndrome. Statistical treatment with using of contingency tables and the calculation of χ2 allowed to determine significant differences between the values. Analysis of the main indicators of the morpho - functional state of the myocardium in patients with ventricular premature beats end tachycardia of WPW-syndrom made possible to identify the most adverse changes in the structure of the heart.
