MEDICAL GADGET OF THE WEEK: KARDIA MOBILE

This small device, barely bigger than a thumb drive, lets you perform EKGs at home in 30 seconds. The Kardia Mobile pairs with a smartphone app (iOS and Android) to find out right away whether your heart rhythm is normal or if something’s amiss. From there, your doctor can make an informed decision about what to do next. Available now, priced at Dh364, alivetec.com.
