An implantable loop recorder is a small device used to continuously monitor the heart’s electrical activity. It stores this information as electrocardiograms (ECGs), capturing irregularities such as arrhythmias or abnormal heart rhythms for later review.

The device records heart activity in two ways: automatically, based on heart rate thresholds set by your physician, or manually, when you activate it after experiencing symptoms.

This recorded data serves as a valuable diagnostic tool and also allows for remote monitoring, helping your care team track your heart health over time.
