It’s the season of gift giving and chances are many people will find smartwatches under the tree next week—think of it as a gift from the heart that helps the heart.

Smartwatches are playing a key role in promoting heart healthy lifestyles and overall wellbeing, with most tracking activity, heart rate, sleep patterns and other fitness attributes.
