Abnormal Heart Rate Feature on Garmin Watches

Newer Garmin watches can notify you when your heart rate unexpectedly goes above a specified threshold. If you are inactive for 10 minutes or more, and your heart rate stays above your set threshold, you’ll get an alert on the watch.  This setting is found under the Heart Rate settings typically accessed from the Heart Rate widget on the watch.  For specific instructions, refer to your Owner's Manual.  

IMPORTANT Garmin watches are not medical devices. The heart rate monitor data is not intended to be used for medical purposes, nor is it intended to diagnose, treat, cure, or prevent any disease or condition.
