Can the Apple 4 smartwatch save lives?

March 28, 2019

The Apple Watch 3 has recently made headlines in a controversial heart study showing its potential use as a screening tool for heart arrhythmias. The Apple Watch 3 is equipped with a set of optical heart sensors to detect your heart rate during exercise.

Theoretically, this means that you could use this device to detect heart arrhythmias in users. Heart arrhythmias affect about 2.7 million people in the US, and contribute to an estimated 130,000 deaths each year.
