[Electrocardiographic changes and hemodynamic comparisons in arterial hypertension]

The electrocardiographic criteria for left-ventricular loading were studied in patients with non-complicated arterial hypertension and were juxtaposed to the basic hemodynamic indices, determined via radio-isotope method--quantitative radiocardiography. Regular changes in the hemodynamics and electrocardiographic criteria were found, in the initial phases within the limits of the norm, and in the later ones--exceeding it. The method of correlation analysis was applied between the separate hemodynamic indisec and electrocardiographic criteria for left ventricular loading both in the separate subgroups and for the whole group. Correlation dependence with various values and sign were found. Finally, it was concluded that the classic electrocardiographic criteria for left ventricular loading in case of arterial hypertension obtained a new meaning and should be assessed with consideration given to the subjects' age and in a comparison with hemodynamic characteristic.
