Anatomical Heart Simulator
Description
The Anatomical Heart Simulator is an interactive educational model for exploring heart anatomy, valve timing, blood circulation, electrical rhythm, and the stages of the cardiac cycle. The anterior cutaway view shows the right and left atria, right and left ventricles, major vessels, heart valves, interventricular septum, and other visible structures while animated blood-flow particles demonstrate pulmonary and systemic circulation.
You can change heart rate, slow the simulation, adjust motion strength, jump directly to different stages of the heartbeat, and turn anatomical labels, blood flow, valve labels, and oxygenation colors on or off. The simulator also includes simplified teaching modes for aortic stenosis, mitral regurgitation, ventricular septal defect (VSD), reduced left-ventricular function, and atrial fibrillation. These condition modes are educational models and are not diagnostic.
How To Use
Start the heartbeat and use the controls to study how the chambers, valves, blood flow, and cardiac-cycle timing change. Click a chamber or valve in the heart diagram to identify it.
| Control | Setting | Action |
|---|---|---|
| Heartbeat | Pause / Play | Pauses or resumes the beating-heart animation. |
| Heart Rate | 40–160 BPM | Changes the physiological heart-rate reference used by the simulation. |
| Simulation Speed | ⅛×–1× | Slows playback so valve motion and blood flow are easier to study without changing the selected BPM. |
| Motion Strength | Slider | Changes the visible strength of the heart's animated movement. |
| Cycle Stage | Buttons | Jump to Filling, Atrial Contraction, Ventricular Contraction, or Ejection. |
| Heart Conditions | Select | Compare Normal, Aortic Stenosis, Mitral Regurgitation, VSD, Reduced LV Function, and Atrial Fibrillation. |
| Anatomical Labels | Toggle | Shows or hides labels for the visible heart structures. |
| Blood Flow | Toggle | Shows or hides animated circulation through the heart and vessels. |
| Valve Labels | Toggle | Shows or hides the tricuspid, mitral, pulmonary, and aortic valve labels. |
| Oxygenation Colors | Toggle | Shows the color distinction used for oxygenated and deoxygenated blood. |
| Heart Diagram | Click | Select a chamber or valve to display information about that structure. |
| Live Cycle | Readout | Displays cycle percentage, beat duration, current stage, and valve state. |
| Reset | Button | Returns the heart simulation to its default state. |
