Overview
The cardiac-cycle study keeps the ECG, Wiggers figure and selected ventricular pressure–volume loop in a consistent arrangement. Live playback moves their phase indicators together. When paused, hover over the ECG or Wiggers plot to explore the cycle. The white ECG marker, vertical Wiggers cursor and PV point move together.
The separate slider has been removed. Moving across either plot updates the highlighted ECG segment, cardiac-cycle phase and current point on the PV loop without changing the disease or intervention. Arrow keys also control time when a plot is focused.
On mobile, tap or drag directly on the ECG or Wiggers plot. Collapse drawers and unnecessary traces to give the figures more room.
