ECG & Vectorcardiogram Simulation

Simulator for and ECG and vectorcardiogram, uses a 12-lead ECG. This is for visualization purposes only.

72 bpm
Simulated 12-Lead ECG
I, II, III, aVR, aVL, aVF, and V1–V6 shown as projections of a shared 3D cardiac vector. Pattern presets approximate classic teaching examples.
Single-Beat ECG Morphology
Segments (P, PR, QRS, ST, T, TP) highlight in sequence as the synthetic cycle advances. Morphology adapts to the selected preset.
Vectorcardiogram
X–Y projection of the instantaneous heart vector.
