Loop Recorder Implant

Implantable loop recorders are a newer generation of heart monitoring devices that allow for the long-term recording of heart rhythm. They are especially useful for infrequent paroxysmal arrhythmias. Loop recorders are advantageous when compared to standard electrocardiograms or EKGs since the latter only offers a snapshot in time and typically miss paroxysmal arrhythmias.

However, loop recorders also have advantages over external heart monitors. Holter and event monitors are worn on the outside of the body and can be bulky and frustrating to wear over the long-term. As a result, most are only used for a few days and once again may miss more occasional arrhythmias.

How Loop Recorders are Implanted

As you can see from the image above, the loop recorder is a very small device and the procedure is similarly minimally invasive. Inserting the monitor is usually performed in the office using local anesthesia. The entire process takes between 30 and 45 minutes and discomfort is very mild and short-lived. We will discuss potential risks during consultation. The implanted device can remain in the body for up to three years but is usually removed or deactivated sooner.

After implantation, the device transmits data to a monitor that is placed on your nightstand. This monitor then transmits heart rhythm data to your doctor. We may also ask you to maintain a journal tracking your activity levels, diet, moods and more.

Despite the loop recorder constantly monitoring your heart rhythm, emergency situations may not be transmitted to your doctor quickly enough. Therefore, if you experience any emergency, do not rely on the loop recorder, but head to your nearest emergency room as soon as possible or dial 911.
