Thanks for the answer.

Long time ago I used a fetal Doppler to detect heart failure in adults. It was not based on LLMs (2016) but on a HMM to learn the hidden states: The heart beats.

It was tested with the Physionet database. It performed quite well, but I didn't invent the algorithm; it came from a Physionet competition.

It could run on low power computers.
