I don't think so. This is not a medical device but rather an aid to track your fitness progress throughout the day. You can see your HR at any time right on the device's screen, but there is no alarm that I know of. It is possible though that you could set a goal for HR just as you set goals for steps and other things and then it would let you know when you have achieved your goal.
I'm a member of the Best Buy Program (but not Elite or Elite Plus). What's the return policy (how many days) for the online purchase of the Samsung Tab Pro 8.4?
