ECG Monitoring (Holter & Event Monitoring)


ECG monitoring is commonly recommended if you are experiencing palpitations, irregular heartbeats, dizziness, or unexplained symptoms. It allows me to monitor your heart rhythm over time while you go about your normal daily activities.

Holter Monitor (24–48 Hour ECG)

If your symptoms occur regularly, I may advise a 24- or 48-hour ECG monitor, often called a Holter monitor or ambulatory ECG.

You will be asked to wear a small, lightweight electronic recorder for one or two days. The device is discreet, painless, and easy to wear under your clothing.

If you experience palpitations or other symptoms while wearing the monitor, you’ll be asked to note the time of the episode. The time is clearly displayed on the front of the device, making this simple to do.

When you return the monitor to us after 24 or 48 hours, we analyse the recording using specialist software. This allows us to match your symptoms with any changes in your heart rhythm, helping us reach an accurate diagnosis.

  • Takes around 5 minutes to fit
  • Removal takes less than a minute
  • Completely painless and non-invasive

Cardiac Event Recorders (Longer-Term Monitoring)


If your symptoms are less frequent, I may recommend a cardiac event recorder, which monitors your heart rhythm over a longer period.

There are two main types of event recorder:

Portable event recorders are small handheld devices that you place against your chest and activate when symptoms occur. These record your heart rhythm at the moment you feel symptoms, helping me detect intermittent heart rhythm abnormalities.

An implantable loop recorder (ILR) sometimes called an injectable loop recorder is a small device placed just under the skin of the chest to continuously monitor your heart rhythm. The procedure is performed under local anaesthetic and is quick-takes less than 10 minutes and minimally invasive. The device can monitor your heartbeat for up to three years, making it particularly helpful for detecting heart rhythm problems that occur infrequently.
