Hello jane,
From the information we have available, I can advise The Garmin Forerunner 255 does not have ECG monitoring capabilities. The ECG feature is available on select Garmin smartwatches, such as the Venu 2 Plus, epix Pro series, and fēnix 7 Pro series.
If ECG monitoring is a crucial feature for you, you might want to consider one of these compatible models.
Thank you for using Q&A
