Beating Heart & ECG Correlation (2D)

2D animated 4-chamber heart synced to a live ECG trace: drive heart rate and contractility sliders and watch valve timing, chamber contraction and the P-QRS-T waveform move together through the cardiac cycle, with live stroke volume, ejection fraction and cardiac output readouts.

Medical Technology & Imaging Physics2DEasy60 FPS📱 Mobile-adapted⇄ 3D version

An interactive 2D diagram of the four-chamber heart beating in sync with a live ECG trace. Adjust heart rate and contractility to see how the P-QRS-T waveform, the four valves' open/closed timing, and the atria and ventricles' contraction all move together through one cardiac cycle, with live stroke volume, ejection fraction and cardiac output readouts.
