Apple Is Said to Develop EKG Heart Monitor for Future Watch

Apple is developing an advanced heart-monitoring feature for future versions of its smartwatch, part of a broader push by the company to turn what was once a luxury fashion accessory into a serious medical device, according to people familiar with the plan. A version being tested requires users to squeeze the frame of the Apple Watch with two fingers from the hand that's not wearing the device, one of the people said. It then passes an imperceptible current across the person's chest to track electrical signals in the heart and detect any abnormalities like irregular heart rates. Such conditions can increase the risk of strokes and heart failure and develop in about one-quarter of people over 40, according to the U.S. Centers for Disease Control and Prevention. These medical tests, known as electrocardiograms or EKGs and ECGs, are common in doctors' offices, hospitals and ambulances.
