METHOD FOR PREDICTING Q-MYOCARDIAL INFARCTION AT NONINVASIVE ELECTROCARDIOGRAPHIC MAPPING THE CARDIAC SURFACE

摘要

FIELD: medicine, cardiology.;SUBSTANCE: it is necessary to register multiple electrocardiographic signals from anterior (a) thoracic wall, detect amplitude values of Q and R waves to plot two-dimensional maps of Q wave duration (Qa), determine on maps Qa areas at wave Q duration being equal or above 0.04 sec. Moreover, additionally, one should register electrocardiographic potentials from lateral, posterior and diaphragmatic walls, plot two-dimensional maps for distributing the sum of amplitude values of a triple Q wave and R wave (Q₃R) in every lead; on Q₃R maps one should detect the areas of negative values. In case of both areas in precardiac region one should diagnose anterior Q-myocardial infarction (Q-MI) of left ventricle, in median-inferior departments of right half of thorax - posterior Q-MI and in inferior departments of thorax - diaphragmatic Q-MI. The innovation enables to detect lesion localization more accurately based upon the data of mapping a patient's cardiac surface.;EFFECT: higher accuracy of diagnostics.;6 dwg, 2 ex
