The Heart as a Map: Topology Reveals Hidden Patterns in Cardiac Rhythm
Each heartbeat can be drawn as a point on a sheet of paper. Thousands of these points merge into a cloud. The Mapper algorithm turns this cloud into a network: it connects points that behave similarly and colors them according to blood flow strength. The result is not just a pile of numbers but a colored map showing which parts of the heart work in sync and which are out of step.
