The surprising story behind the Apple Watch’s ECG ability


The Apple Watch produced a seismic shift in the public’s acceptance of biometric monitoring. Sure, we’ve had step counters, heart rate and sleep monitors for years, but the Apple Watch made it hip and cool to do so. In Deep Medicine, author Eric Topol examines how recent advances in AI and machine learning techniques can be leveraged to bring (at least the American) healthcare system out of its current dark age and create a more efficient, more effective system that better serves both its doctors and its patients. In the excerpt below, Topol examines the efforts by startup AliveCor and the Mayo Clinic to cram an ECG’s functionality into a wristwatch-sized device without — and this is the important part — generating potentially lethal false positive results.

Apple is just scratching the surface of its health care efforts.
