Often, the irregularity of random symptoms can come and go, so monitoring them is difficult. If standard tests have not provided answers, an implantable loop recorder (ILR) may be an option. This small device continuously monitors your heart’s electrical activity, helping to detect hidden rhythm issues over time.

What is Implantable Loop Recorder Insertion?

An implantable loop recorder (ILR) is a tiny device placed under the skin that records your heart’s activity for a long period of time. Unlike external monitors, which only track rhythms for a few days, an ILR provides long-term data to doctors. This helps identify irregular heart rhythms that may not appear during short-term testing. 

The procedure is quick and minimally invasive. A small incision is made, usually near your chest, and the device is inserted just beneath your skin. The ILR continuously records your heart’s activity and can automatically detect abnormal rhythms. You may also be given a handheld remote to monitor symptoms when you feel something unusual.

Who might need an ILR?

An implantable loop recorder may be recommended if you have:

  • Unexplained fainting or dizziness.
  • Irregular heart rhythms that are difficult to record.
  • Symptoms that indicate an underlying heart condition but remain undiagnosed.

This device is especially helpful if your symptoms do not occur often. It provides a detailed and long-term picture of your heart’s activity, giving doctors the information needed to diagnose.

How should I prepare for the procedure?

Before the procedure, you may be asked to:

  • Avoid eating or drinking for a few hours.
  • Adjust certain medications as instructed by Dr Mtwesi.
  • Wear loose, comfortable clothing on the day of the procedure.

The procedure itself is performed under local anaesthesia. It usually takes less than 30 minutes, and most patients go home on the same day.

What happens after the procedure?

Aftercare is simple, and Dr Mtwesi will guide you on what you can and can’t do while you heal. Some common things you must remember are the following:

  • Keep the incision area clean and dry.
  • Do not engage in strenuous activities for a short period.
  • Follow up with your doctor to review heart activity.

The device works silently in the background and requires no daily upkeep. If your doctor detects an irregularity, you will be contacted to discuss the next steps.

When should I consider an ILR?

If you have experienced unexplained symptoms and short-term heart tests have not found a cause, an implantable loop recorder may help. Tracking your heart’s activity over time can give doctors valuable insights so that we can make more informed decisions about your health.
