Model-Based Method and Instrumentation for Noninvasive Identification of Local Ischemic Lesions in the Heart

Popis výsledku v původním jazyce

An inverse method for identification of possible local ischemic lesions is presented. Body surface potentials recorded in conditions with and without manifestation of ischemia were used to evaluate changes in time integrals of surface potentials caused by changed repolarization of ischemic myocardial cells. Surface distribution of integral differences together with information on torso volume conductor was used to find an equivalent electric generator with one or two dipoles representing the ischemic lesions. Compact system for multichannel ECG measurement and evaluation with an intelligent battery powered data acquisition unit that enables simultaneous recording of up to 128 torso leads was developed. Active electrodes and optical connection to the controlling computer were used to achieve high signal quality and patient safety. Software for ECG acquisition and evaluation of isointegral surface maps was applied for location of one or two dipoles representing myocardium areas with chan
