METHOD AND DEVICE FOR RECORDING MULTIPLE LEADS OF ELECTROCARDIO SIGNAL Russian patent published in 2022 - IPC A61B5/318 

FIELD: medicine.

SUBSTANCE: inventions group relates to medicine, namely to a method for recording leads of an electrocardiosignal (ECS) and a device for its implementation. In this case, the pacemaker is recorded, as well as the electrophysiological characteristics of the heart are determined and visualized. At the stage of registration of the pacemaker, the size of the damage to the epicardium in the plane of the cross-section of the torso is set according to the formula , where is the size of the damage to the epicardium; is the size of the area of damage to the epicardium. The angle γ between the radii R_heart of the sphere describing the heart in the plane of the cross-section of the torso is determined by the formula , where is the size of the damage to the epicardium, i.e. the length of the arc on the surface of the sphere in the plane of the cross-section of the torso. The number of k_el points of registration of potentials in the plane of the cross-section of the torso and the coordinates x and y of the electrodes in the plane of the cross-section of the torso are determined. The distance d_el between the rows of electrodes is set. The number of electrodes is determined by the formula , where is the number of rows of electrodes, [] is the designation of the integer part of the number, and L_z is the size of the torso region that encloses the heart in the plane of the vertical section of the torso. The device for recording ECS leads contains a serially connected module for recording ECS leads, a module for collecting, processing and storing data, and an analysis and visualization module. The registration module is implemented in the form of a vest with pre-installed N_el electrodes located evenly along the length of the contour l of the torso cross-section in r_el rows and connected by means of a harness, and contains serially connected analog and digital parts. The analog part contains N_el parallel channels for the transmission of ECS lead signals. The digital part contains a series-connected ADC, a computing device and a data reception/transmission unit.

EFFECT: invention provides non-invasive determination of the electrophysiological characteristics of the heart with increased accuracy using the number of electrodes required to identify the minimally soluble myocardial damage by means of electrocardiography, with a decrease in the complexity of the pacemaker registration process by the patients themselves at home.
