Cardiosomnography

I demonstrate in my recent paper that it is now possible to score sleep at equivalent performance to expert human-scored polysomnography (PSG) using only ECG. Therefore, I proposed the term “cardiosomnography” (CSG) for any sleep study conducted exclusively using electrocardiography (ECG/EKG) data.

My intention is for CSG to take more expert-level sleep studies outside the confines of clinics and laboratories and into realistic settings—with just a chest strap. By eliminating the need for the most cumbersome equipment and manual scoring, it makes less-expensive, higher-quality studies more widely accessible.

For more information, check out the website, cardiosomnography.com, where I’m also keeping a project-specific blog. However, I’ll also be crossposting everything here, with the tag cardiosomnography.

If you’re curious about the history and future plans for CSG, read more here.

Finally, I’ve released all of the source code on GitHub, where you can find everything you need to score your own sleep data and replicate the paper.
