The internal loop recorder monitors the heart rhythm for more than three years and is indicated for detecting the cause of repeated, unexplained loss of consciousness. Only abnormal heart rhythms or activated recordings are stored as relevant information.

Preparation

You will be admitted to the Cardiology Day Hospital. You do not need to have fasted and you may take your usual medication. Sometimes, blood samples will be collected.

You will be given a surgical gown. Shortly before the procedure, you can be provided with a tablet to help you relax. The nurse will place an IV line in your arm to administer medication, should that be necessary.

The procedure will be performed in the Cardiac Catheterisation Laboratory.

Procedure

You will be placed on the treatment table. Adhesive electrodes are placed to monitor your heart rhythm. An area of skin measuring 10 by 10 cm is shaved and disinfected, and adhesive sterile sheets are placed around it. A local anaesthetic is injected to numb the skin and the underlying subcutaneous tissue next to the breast bone. The physician makes a small incision of 15 mm, and a space is created between the subcutaneous tissue and the muscle. The device measures 6 by 2 cm, is 8 mm thick and is placed in the space created. The skin is closed with absorbable sutures and the wound is covered with a plaster.

Aftercare

The plaster must stay on for a few days in order to prevent infection. Do not shower or bathe in the first days after the procedure.

What are the risks?

What are the risks?

Localised bruising is possible, but it does not require much looking after.

In very rare cases, and despite the precautions taken, the wound may become infected. In the event of infection, antibiotics must be administered and/or the device must be removed.

Results

Results

The device will automatically record heart rhythm disturbances. However, if you use the remote control, you can also record information in case you experience symptoms like dizziness or fainting. You will be seen by a physician in the outpatients clinic every few months. If you have made a recording yourself after having fainted, please make an appointment promptly. The data on the device will be downloaded onto a computer and assessed by a physician. Once relevant heart rhythm disturbances have been identified, further treatment can be adjusted (e.g. through medication, pacemaker).
