Controls

Presets

Each heartbeat is an electrical wave: a fast sodium upstroke, a long calcium plateau unique to heart cells, then potassium repolarization. That plateau keeps the muscle contracted long enough to pump — and its length sets the refractory period. Educational tool, not medical advice.

Governing equation

Reading this result: The plateau holds the cell near 0 mV for ~343 ms — the calcium phase unique to heart muscle that keeps it contracted long enough to pump before potassium repolarizes it.

About this simulation

The full Cardiac Action Potential tool models a metabolic pathway with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions

How do I simulate a metabolic pathway?
Open this page and use the live Cardiac Action Potential tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
Is it free?
Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
Can I use my own numbers?
Absolutely — every input is adjustable, and with data import you can drive a metabolic pathway from your own measurements.
