What Is An Implantable Loop Recorder?


In this article:

An implantable loop recorder is a monitoring device that aids in the investigation of the origins of some cardiovascular issues. This device can collect data that a typical electrocardiogram or Holter monitor might miss. This article will explain more about this device, including what it is, who requires it, how it works, and any potential adverse effects.


Everything You Should Know About A Loop Recorder Implant

What Is An Implantable Loop Recorder?


An implantable loop recorder is a heart-monitoring device that continually records your heartbeats, allowing your doctor to monitor your heart rhythm from afar. This device has various applications, one of which is to search for causes of fainting, palpitations, fast/slow heartbeats, and hidden rhythms that might cause strokes.


Who Needs An Implantable Loop Recorder?


For those who faint regularly but not often enough for other types of heart rhythm monitoring to detect their fainting, a loop recording implantation might be a good option. Irregular heartbeats might result in palpitations or even strokes. Certain types of fainting also carry a higher risk of sudden death.

The loop recorder can function for up to three years, allowing the healthcare professional to look for particularly fast or sluggish heartbeats. The healthcare provider can evaluate one’s cardiac rhythms during a fainting episode, thanks to the implantation.

In addition, this device might also be helpful for older adults experiencing inexplicable falls. In this circumstance, the recorder can tell if there is an irregular beat.


How Does An Implantable Loop Recorder Work?


Your cardiologist will implant the recorder beneath your skin on the chest wall above your heart. The device functions as an electrocardiogram, collecting electrical signals from your heart. This aids in diagnosing abnormal cardiac rhythms, leading to specific cardiovascular problems, such as fainting.

Specific cells in the sinoatrial node typically initiate the electrical impulse that starts your heartbeat. The signal swiftly goes through the two lowest chambers of your heart, from the conducting system to the ventricles. As the signal travels, it triggers nearby portions of your heart to contract, allowing your heart to pump blood in a coordinated manner.

If this signalling system is disrupted for any reason, heart rhythm issues may occur, including fainting and palpitations. Due to an irregular cardiac rhythm, your heart will not be able to pump sufficient blood, leading to fainting caused by a temporary reduction in blood flow to your brain.


What Are Side Effects Of Loop Recorder Implantation?


The majority of people use the device without any issues. However, some issues to be vigilant about could include:

  • Bruising or bleeding
  • Infection
  • Damage to the blood arteries
  • Discomfort in the device location


Through regular checkups, your doctor will evaluate the results and contact you if there are any concerns. An implantable loop recorder is invisible and leaves no effect on your regular activities. It’s considered safe to use during magnetic resonance imaging (MRI). However, before scheduling an MRI test, it’s a good idea to inform your doctor about your implant.
