Noninvasive localization of ectopic ventricular activity using BSPM and different patient torso models

Popis výsledku v původním jazyce

The possibility of noninvasive localization of the focus of ectopic ventricular activity and dependence of its accuracy on the used heart and torso model were examined. Body surface potentials were measured in 62 leads in two patients with idiopathic extrasystoles having the focus in different ventricular regions assessed by intracardiac electrophysiological study. Integral maps over the initial period of the premature ventricular activation and inhomogeneous torso model were used as input for an inverse solution to find noninvasively the focus of the premature activation represented by a single dipole. Three torso models representing the individual patient torso with different fidelity were attempted. The best agreement between the focus positions obtained from the inverse solution and from the electrophysiological study was achieved when the torso and heart model based on whole-torso CT was used. The use of an individually adjusted general torso model and properly positioned heart mo
