Key result
Volumetric electrocardiographic imaging reduces geodesic error by ~59% in estimating arrhythmia origins versus surface-only approaches.
Why the study?
Conventional electrocardiographic imaging is restricted to epicardial reconstructions, reducing its reliability in accurately identifying arrhythmias arising from deeper myocardial structures.
Does volumetric electrocardiographic imaging improve the localization of arrhythmia origins compared to surface-only approaches?
Does volumetric electrocardiographic imaging improve the localization of arrhythmia origins compared to surface-only approaches?
Effect estimate: 59.3% reduction
Volumetric electrocardiographic imaging provides accessible, non-invasive 3D mapping of cardiac activation, improving arrhythmia localization accuracy over conventional epicardial methods.

Volumetric electrocardiographic imaging improves arrhythmia origin localization; extends non-invasive 3D mapping beyond surface-only approaches in randomized evidence.
Vicente-Puig et al. (2026) studied Cardiac arrhythmias (n=4). Volumetric electrocardiographic imaging vs. Surface-only approaches was evaluated on Geodesic error between estimated and simulated origins (59.3% reduction). Volumetric electrocardiographic imaging yielded a 59.3% reduction in geodesic error between estimated and simulated arrhythmia origins compared to surface-only approaches.
