[Comparative electro- and vectorcardiographic study of patients with systolic overloading in the left ventricle]

The potentialities of the two methods for hemodynamic disturbance degree assessment are studied in 80 patients with arterial hypertension (16-first stage, 59-second and 5-third). Five electrocardiographic and five vectorcardiographic indices are confronted to the systolic pressure in brachial artery. The electrocardiographic indices sensitivity is in the range of 25 to 62% and the sensitivity of vectorcardiographic-from 14 to 50%. The correlation dependence level of the same indices (in 30 patients) is from 0, 37 to 0, 52 for ECG and from 0, 11 to 0, 60 for VCG. Statistically significant differences of the "diagnostic" potentialities of both methods were not established as well.
