CAN APPLE WATCH MEASURE BLOOD PRESSURE? NOT YET — BUT HERE'S HOW THE SCIENCE WOULD WORK.

Summary from the TLDR newsletter

This post explains the science behind blood pressure detection on the wrist, past medical literature on using deep neural networks to glean signals from consumer wearables, likely limitations of wrist-based blood pressure sensors, and how doctors and patients can incorporate the technology into medical practice. 120 million people in the US have been diagnosed with high blood pressure, but only 23% have it under control. A continuous blood pressure monitor could help give real-time feedback on dietary choices and help control the condition, which in turn could lower heart attack rates.
