  • The electrodes are connected to a device that records your heart’s rate and rhythm.
  • The installation of electrodes and monitor takes approximately 15 minutes.
  • The monitoring period lasts from 24 to 48 hours. During this time, you will have to keep track of your symptoms and activities in a diary.
