ECG smartwatches

  • 205 smartwatches

With ECG smartwatches, you can measure your heart rate based on the electrical signals in your blood. These signals measure the rhythm and strength of your heart rate. This is useful as your smartwatch notifies you when your heart rate is too high or irregular. That way, you can learn about your health. When in doubt, always visit a doctor.
