METHOD AND DEVICE FOR DETECTING MYOCARDIAL INFARCTION AND DETERMINING ITS LOCALIZATION Russian patent published in 2003 - IPC

FIELD: medicine; medical engineering. SUBSTANCE: method involves comparing electric mobility of two neighboring myocardium areas in two leads. Sharp drop in tangent inclination with respect to harmonic spectrum envelope in the cases of various signs of tangent slope being found, infarction is considered to be available. The lead number showing negative tangent slope value is interpreted in terms of infarction lesion position. The device has movable body, two contact plates, two conductors connecting the plates to the receiving devices, two identical units for measuring heart beat periods, two analog-to- digital converter and two computation units for calculating tangent inclination angles to harmonic spectrum envelopes of QRS- complex biopotentials taken at the places the contact plates are positioned. The device has unit for measuring output signals ratio of both computation units connected to acoustic or luminous level signalization unit. EFFECT: high accuracy and reliability of measurements. 2 cl, 1 dwg, 1 tbl
