Risks
By Mayo Clinic staffThere are no significant risks involved in wearing a Holter monitor. The device doesn't transmit electricity, so there's no risk of electric shock.
However, the Holter monitor can't get wet, or it will be damaged. Don't swim or bathe for the entire time you're wearing your Holter monitor. While Holter monitors aren't usually affected by other electrical appliances, you shouldn't walk through a metal detector while wearing one.
