Computer applications to body-surface electrocardiograms.

Changes in Body-Surface Electrocardiograms from Geometric Remodeling due to Obesity

Both diabetes and obesity are responsible for deleterious changes to the heart. To separate consequences of geometric changes from electrophysiologic ones, we investigated how changes in cardiac and torso geometry, associated with obesity, affected body-surface electrocardiograms. For this study, we modified the realistic heart and torso models of the simulation package ECGSIM. Body-surface pot...

Software design for analysis of multichannel intracardial and body surface electrocardiograms

Analysis of multichannel ECG recordings (body surface maps (BSMs) and intracardial maps) requires special software. We created a software package and a user interface on top of a commercial data analysis package (MATLAB) by a combination of high-level and low-level programming. Our software was created to satisfy the needs of a diverse group of researchers. It can handle a large variety of reco...

The Use of Simultaneous Multichannel Endocardial and Surface Electrocardiograms for Verification of Exit Site Localization Using Body Surface Mapping

Exit sites of monomorphic ventricular tachycardia and focal sites of ventricular extrasystoles can be localized using an endocardial catheter in conjunction with a multichannel surface ECG, in order to find a suitable site for ablation. For this procedure, as well as for the diagnosis of these types of arrhythmia it is desirable to know the relation between surface ECG and site of origin accura...
