Live ECG graph in WPF

What would be the best (simple and fast) approach to plotting live ECG data in a WPF application? I am thinking about writing my own control that will use paths to render the signal. But maybe there are ready-to-use graph libraries that suit my needs? Do you have any experience in this area?

Thanks for all your answers, however all third-party components using Saved Graphics were too slow. I decided to use a double buffered WritableBitmap with unsafe code and image control.

You may be able to use the Dynamic Data Display . Its very flexible and performance is superior to any commercial product I've tried.

LightningChart is fast enough. It works in WPF according to the docs. However, I've only used it in WinForms.

I know Visifire has live update and line graph. I'm not sure if it's enough for your needs though. But it's free until you sell and open something.
