Loop Recorders
An implantable loop recorder (ILR), also called an insertable cardiac monitor, is a small device placed just beneath the skin of the chest to continuously monitor your heart rhythm. Unlike external heart monitors that are worn for a few days or weeks, an ILR can monitor heart rhythms for up to several years.
An ILR helps your provider detect abnormal heart rhythms that may occur infrequently and are difficult to capture with short-term monitoring.
WHY
Is an ILR Used?
An implantable loop recorder may be recommended to:
Evaluate unexplained fainting, dizziness, or lightheadedness
Investigate heart palpitations
Detect atrial fibrillation (AFib) and other arrhythmias
Monitor known heart rhythm disorders
Evaluate heart rhythm after a stroke or other cardiovascular event
Identify abnormal heart rhythms that occur infrequently
WHAT TO EXPECT
The device is placed beneath the skin through a small incision during a minimally invasive outpatient procedure. The procedure is typically performed using local anesthesia and generally takes only a few minutes.
BENEFITS
of an ILR
Potential benefits may include:
Long-term heart rhythm monitoring
Detection of infrequent arrhythmias
Improved diagnosis of unexplained symptoms
Continuous monitoring without external wires or patches
Important Note
Your cardiologist or electrophysiologist will determine whether an implantable loop recorder is appropriate based on your symptoms, medical history, and overall cardiovascular health.
