What is an Implantable Loop Recorder?
An implantable loop recorder is a small electrical device that is able to continuously record the heart activity. It is often used to help find a cause for recurrent unexplained syncope when there is a strong suspicion of a heart rhythm cause but all other simple tests have been normal. It can also be used to monitor patient’s heart rhythm after atrial fibrillation ablation procedures.
