@Ledbetter Welcome to the Fitbit Community! Try to perform a restart on your Surge. Also, make sure you are not using the tracker too tight on your wrist as that may affect the readings. Using the tracker a bit higher on your wrist (two fingers from your wrist bone) is also recommended. Feel free to check the Heart Rate FAQs for more details.
Let me know how it goes!
