Ask HN: Heartbeat from ECG?

2 points by aliirz 6 years ago | 1 comment

I recently lost my mother to cancer. For some reason, this idea is stuck in my head that if I hear her heartbeat it will make me feel a lot better. Is it possible to generate the heartbeat sound using an ECG image using computer vision and ML?

You don't need that fancy tools. An RGB camera with simple linear filters will give you an rPPG signal if you are stationary. And then you can trigger a sound from each detected top.

You can also buy cheap ppg readers that are very easy to use.

However: one defect by using PPG is that you will have a delay between heartbeat and signal due to the time for the blood to move.

Or you could work on the fear...
