METHOD FOR DIFFERENTIAL VECTORCARDIOGRAPHY Russian patent published in 1999 - IPC

FIELD: medicine, in particular, functional diagnosis. SUBSTANCE: a great number of leads located on the surface of the chest are registered at 5 levers in the horizontal plane at an equal distance from one another. The amplitudes of waves of the electrocardiographic curve in each lead are calculated, and vectorcardiograms are plotted - schedules of spatial distribution of the amplitude values of separate waves Q, R, S, T, segment ST, as well as QR of the vectorcardiogram, on the basis of the data obtained by subtraction of triple modulus of wave Q from modulus of wave R in each lead. And the Q⁵S vectorcardiogram is plotted on the basis of distribution of moduluses of amplitudes of wave S and quintuple wave Q in each lead against the background of vectorcardiograms of norms. EFFECT: enhanced truth of diagnosis of some diseases of the cardiovascular system. 1 cl, 2 dwg, 2 ex
