Figure Lengend Snippet: Schematic diagram of the study. A: patients; B: body surface ECG collected pre-surgically including the arrhythmias; C: CT scan with torso and cardiac geometry; D: EP study with catheter ablation by intra-cardiac mapping technique; E: BSPM of the ectopic beats isolated from the ECG recording. F: boundary element model constructed according to the CT geometry; G: 3D co-registration of CARTO geometry and CT endocardium; H: CESI activation in 3D; I: quantitative comparisons between the CARTO mapped activation pattern and the CESI activation pattern on corresponding regions.

Article Snippet: Triangular meshes of the realistic geometry (torso, lung, epicardium and myocardium) and ECG recordings were exported to the customized CESI software developed in Matlab 2010a (Math Works, Natick, MA).

Techniques: Computed Tomography, Isolation, Construct, Activation Assay

Figure Lengend Snippet: Examples of imaging activation sequences during ectopic beats originating from the RV (Panel A) and the LV (Panel B) in two patients. Black circles represent the last successful ablation site. The white star indicates the site of initiation localized by CESI. The left column shows the 3D volumetric view of the myocardium activation. The cross-sections along the axial direction are presented in the middle column. In the right column, the endocardial surface is extracted from the 3D imaged activations and compared with those measured by CARTO.
