[Significance of Electrocardiography in Patients With Arterial Hypertension].

The article is devoted to the analysis of significance of electrocardiography for assessment of anatomical-functional measurements of the heart in patients with arterial hypertension. Modern methods of calculation of the left ventricular myocardial mass are presented with corresponding recommended normal ranges values. The article contains discussion of variants of left ventricular remodeling, significance of functional indexes characterizing the state of systolic and diastolic function of the heart, parameters of deformation of the left ventricle for diagnosis of causes of left ventricular hypertrophy, as well as for assessment of prognosis.
