Abstract
In one embodiment, a cardiac mapping system includes a medical examination device to capture data over time at multiple sample locations over a surface of at least one chamber of a heart, a display screen, and processing circuitry to process the captured data to determine a description of a propagation of activation wavefronts associated with activation times over the surface of the at least one chamber of the heart, calculate activation wavefront propagation path traces wherein each path trace describes a point on one activation wavefront being propagated over the surface of the at least one chamber of the heart according to an advancement of the activation wavefront such that the path traces describe the propagation of different points according to corresponding activation wavefronts, prepare a visualization showing the path traces on a representation of the at least one chamber, and render the visualization to the display screen.
