The Edan-Waterfall Plot functions is an advanced clinical diagnostic software module designed for the Edan Holter Analysis System. This specialized feature provides a three-dimensional visual representation of sequential ECG segments or heart rate variability data over extended monitoring periods. By stacking consecutive waveforms, the waterfall graphic allows clinicians to instantly spot transient morphological changes, ST-segment shifts, and evolving ventricular arrhythmias that might otherwise be missed in traditional flat data views.
