Noninvasive system for localization of small repolarization changes in the heart

Original language description

Novel noninvasive method for localization of areas of myocardium with changed repolarization that can lead to life threatening cardiac arrhythmias is presented. Method is based on multichannel ECG measurement, body surface potential mapping and solving the inverse problem of electrocardiology to find one or two dipoles representing the pathological sources in the heart. Body surface potential mapping system ProCardio-8 using up to 144 active electrodes was used for multichannel ECG measurement. For theinverse calculations, inhomogeneous model of the shape of thorax with lungs and ventricles including cavities was used. Ability of the system to identify selected cardiac pathologies is demonstrated on cases with one or two ischemic foci. In this paper,analysis of existing system and algorithms for cardiac pathology localization is given in detail. Further software development will include ventricular premature beat foci localization.
