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 modified in real-time.

ECG Simulation

Real-time ECG waveform simulation based on the McSharry ECG model.

Controllable Heart-Rate Variability Engine.

Adjustable heart rate and waveform parameters.

Swap between different pathological condition.

Rendering Modes

Material Mode (GPU)

GPU waveform rendering using signed distance fields. Can apply the material to any surface and have the image be corrected for 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.
