Loop Recorder

A loop recorder, also known as an implantable loop recorder (ILR), is a small device that is implanted under the skin of the chest to continuously monitor the heart's electrical activity. It is used to record and store heart rhythm data for a long period of time (up to 3 years), and can be activated by the patient  when symptoms occur. It  is programed to detect dangerous arrhythmias and automatically send them to your doctor for review. 

The loop recorder implantation procedure is typically done in a hospital or clinic under local anesthesia, and takes about 45 minutes.

 

During the procedure, a small incision is made in the chest, and the device is inserted under the skin and anchored to the chest wall using sutures.  Most people do not report significant pain during or after the procedure, but some may experience mild discomfort or soreness in the area for a few days.

Loop recorders are commonly used to diagnose conditions such as:

  • Syncope (fainting spells)

  • Palpitations (rapid or irregular heartbeats)

  • Atrial fibrillation (irregular heartbeat in the upper chambers of the heart)

  • Brugada syndrome (a genetic disorder that can cause sudden cardiac arrest)

  • Arrhythmias (abnormal heart rhythms)

  • Cardiac conduction disorders (disorders of the heart's electrical system)

Possible Complications:

Loop Implant is considered a safe and effective procedure with relatively low risks of complications. Patients who undergo port placement should be closely monitored for any signs of infection, bleeding.
