Your Apple Watch says you have a heart condition. Now what?

Just because your smartwatch can tell you if you have an irregular heart rhythm, does that mean the information will do you any good?

Many new smartwatches, including those from Apple, have sensors that can pick up on an irregular pulse and notify wearers that they may be in atrial fibrillation, or AFib. The devices are hitting the market at a time when consumers are gaining interest in tracking aspects of their health beyond fitness.
