Precautions
Don’t take the Holter monitor off — it must be worn during the entire recording period, even while sleeping.
During the process
A Holter monitor is typically worn for 1 to 2 days. During that time, the device records all of the heartbeats.
Holter monitoring is painless and non invasive. The sensors (electrodes) and wires can be hidden under clothing. The device is worn on a belt or attached to a strap.
Don’t take the Holter monitor off — it must be worn during the entire recording period, even while sleeping.
After the Process
Once your monitoring period is over, you’ll return the device to your health care provider’s office. If you were asked to keep a record of symptoms that you had while wearing the device, your provider can compare the Holter monitor’s data with your notes. This can help your provider make an accurate diagnosis.
