Implantable Loop Recorder (ILR)
An implantable loop recorder, or ILR, is a heart recording device that is implanted in the body underneath the chest skin. Its purpose is to diagnose an underlying arrhythmia that may be causing fainting, palpitations, very fast or slow heartbeats, and hidden rhythms that can lead to strokes. It can store the pattern of activity that happens before, during, and after an “event.” By analyzing the stored data, your physician can determine whether the cause is a rhythm problem and can treat you accordingly.
