Rooted in a 1975 MIT project to digitize ECG recordings for arrhythmia research, the platform evolved from mailed magnetic tapes to a global repository hosting hundreds of databases. Today it is cited by more than 15,000 scientific publications annually and used by researchers in over 180 countries. Originally focused on cardiovascular signal processing, PhysioNet now hosts electronic health records, imaging data, and AI models, and has become a cornerstone for healthcare AI research. Its open data-sharing model, once considered revolutionary, is credited with lowering the cost of ambitious research and accelerating biomedical discovery worldwide. ## Full article daily.dev links to this article rather than hosting it.
