Assessment of heart position in a torso model using an inverse solution

Popis výsledku v původním jazyce

Knowledge of actual heart position is important for finding results in inverse problem of electrocardiography. Magnetic resonance images of real subjects revealed large variability of the heart position in relation to ecg lead V2 usually placed in the 4th intercostal space and considered as the anatomical reference. The use of standard torso model in which the location of modeled heart is constant thus cannot reflect its actual position sufficiently. The method for finding the approximate position of heart in a standard torso model corresponding to the actual heart position in an observed subject is presented. Position of single dipole obtained by an inverse solution from body surface potential measurements was used to locate the initial site of ventricular depolarization and suggested as representative position of the left ventricular septum. This approach was studied in 25 subjects with well documented geometry and measured ecg potentials in 62 leads. For each subject the heart in st
