Make a small home machine that can take an EKG and tell you if everything is fine, or if you should go get checked.
Adjust it to give some false positives, but no false negatives.
Make it cost around $50, and make sure it's fully reusable (i.e. you can borrow one from a friend for a quick check).
If machine learning is not up to the task, then send the EKG to a doctor, I believe they can read them in just seconds (correct me if I'm wrong), so it should not be expensive per-person.
To simplify it, have it connect via bluetooth to a phone, so you don't need to worry about WiFi, or a display. For reliability have it store the last 10 readings, even if not connected, so it should have a start button and indicator lights.

Might be a good idea! Just don't stop there and be more ambitious. Kill the heart attack market as much as you can by making this technology widely available to those that need it at no cost. Find different ways to earn something from it...
If there is one thing that has been proven over and over again, it's that the market and health care don't go together in terms of efficiency. I'm not even touching the ethics angle here...
When I hear the n-th iteration of the basic income discussion and the "useless" class, health care strikes me as the area to make a real difference in, much more than "basic income". Because even the "useless" class will find ways to sustain itself, given adequate health.

* go see a doctor
* urgently go see a doctor!
No, just put 24-hour machines in malls, then you don't need to delay going to market trying to get it under $50
