Loop Recorder

Also known as: Implantable Loop Recorder, ILR

Duration: Variable

The loop recorder is an implantable device that continuously monitors the heart’s electrical activity for up to 3 years (in comparison to the Holter or Event monitors). This is a helpful test when others have failed to diagnose the cause for conditions like syncope, cryptogenic stroke, or palpitations/arrhythmias and to develop treatment plans.

Uses:

• Mainly to figure out the cause of multiple fainting/syncope episodes
• In older adults with no known reason for falling
• Irregular heartbeats (arrhythmias)
• Cryptogenic stroke

How is the test performed:

• A local anesthetic will be given to help you relax.
• A minor incision is then given to place the device in your chest (under the skin) near your heart.
• Once the loop recorder has been implanted, it works as a continuous EKG.
• The incision will be closed and a bandage will be placed over it.
• You will be asked to keep a transmission monitor by your side to continuously record the data.
• Your cardiologist will monitor the data that is gathered.
• You will also be asked to keep a log to write down details of any symptoms you may be experiencing.
