Interpolation of body surface potential maps.
The performance of four methods for interpolation of body surface potential maps (BSPMs) for different electrode grid densities was assessed. This study is part of a research project on the influence of the variability of 12-lead electrocardiograms on computer interpretation due to small electrode position changes. Interpolated BSPMs can be used to simulate this variability. The set of BSPMs st...
متن کاملSources of variability in normal body surface potential maps.
Within-group variability of body surface potential maps was assessed on data from 685 carefully validated normal subjects (348 men and 337 women). Sources of within-group variability were evaluated by subgrouping maps by patient sex, age, height, and weight. Contribution of reproducibility error to total variance was assessed in a separate group of 52 normal subjects in whom multiple maps were ...
متن کاملAssessment of Heart Repolarization Properties from Body Surface Potential Maps
Use of activation-recovery interval (ARI) in surface ECG leads as possible indicator of changed repolarization in the underlying myocardium was studied. Model ECG data representing normal and pathological myocardium repolarization were simulated on surface of realistic inhomogeneous torso. Results of simulations suggest that shortening and prolongation of action potentials in anterior myocardia...
متن کاملIdentification of Patients at Risk for Ventricular Tachycardia by means of Body Surface Potential Maps
In this work we attempted the stratification of patients at risk for VT by means of BSPM recorded during sinus rhythm, based on the evidence that specific arrhythmogenic alterations manifest on body surface potentials. Due to the high dimensionality of BSPM data and the limited number of available patients, a feature extraction step was necessary prior to the classifier design. Feature extracti...
متن کاملAssessment of Number of Lesions from Integral Body Surface Potential Maps
•One or two lesions in different positions in the ventricular myocardium were modelled and corresponding BSPMs (body surface potential maps) were calculated on the surface of an inhomogeneous torso model using the multiple dipole cardiac generator [2]. Twelve combinations of two ischemic lesions were adopted, each with eight variations in size and shape. Together 96 pairs and 48 single lesions ...
