AI can hear a cardiac arrest by Timothy Revell in NewScientist 13 January 2018 - The Sentient Robot

Corti, an AI start-up, has developed an algorithm that can spot imminent heart failure in people calling up emergency services. At the moment, the algorithm is just working on what the callers are saying. This involves the actual words, i.e., natural language processing. It has been trained on emergency call logs going back years. But there is no reason in principle why it could not analyse intonation and breathing patterns from the calls too.
