Estimation and validation of cardiac conduction velocity and wavefront reconstruction using epicardial and volumetric data
Cardiac conduction velocity (CV) is an important electrophysiological property that describes the speed and direction of electrical propagation through the heart. Accurate CV measurements provide a valuable quantitative description of electrical propagation that can help identify diseased tissue substrate and stratify patient risk. In this study we explored a range of techniques for estimating epicardial and volumetric CV and validated the performance of the techniques using whole heart image-based computational modeling. The CV estimation techniques implemented in this study (streamlines, triangulation, inverse-gradient) produce accurate, high-resolution CV fields that can be used to study propagation in the heart experimentally and clinically...
