How to use the Garmin ECG feature

Heart health is critical, and for some, having the ability to monitor heart rate and heart rhythms can be an invaluable tool. That’s especially true for anyone with worrying symptoms, such as lightheadedness when working out, or those who have been diagnosed with an irregular heart rhythm called AFib. An electrocardiogram, or ECG, is the test used to detect irregular heart rhythms by measuring electrical signals in the heart. Until recently, though, getting an ECG required a visit to a doctor.
