CardioSim

Real-Time ECG Simulation for Unity 6

CardioSim is a real-time electrocardiogram (ECG) simulator for Unity based on the
McSharry ECG model.

It generates physiologically realistic ECG waveforms that can be modified in real-time.

Links

Installation

  1. Download the appropriate .unitypackage file from HERE.
  2. Drag the package into the Assets folder of your Unity project.
  3. Add the Heart and ECGVisualizer components to a GameObject.
  4. Select a rendering mode.
  5. Configure the renderer or material depending on the visualization backend you want to use.

ECG Simulation

  • Real-time ECG waveform simulation based on the McSharry ECG model
  • Controllable Heart-Rate Variability engine
  • Adjustable heart rate and waveform parameters
  • Switch between different pathological conditions

Rendering Modes

Material Mode (GPU)

GPU waveform rendering using signed distance fields.

  • Apply the material to any surface
  • Automatically corrects waveform aspect ratio
  • Customizable grid and background colors

Mesh Mode (CPU)

  • Generates a procedural mesh at runtime to display the waveform

Custom Mode

  • Implement your own ECG rendering backend by creating a renderer that implements the
    IECGRenderer interface.

Compatibility

  • Unity 6+ (6000.x and newer)
  • URP supported
  • Desktop and WebGL fully supported
