What is ambulatory ECG Holter monitoring?

The holter monitor is a lightweight device that you wear. Ambulatory ECG recording allows a cardiologist to analyse your heart rhythm for a period of anywhere from 24 hours to one week – ‘ambulatory’ simply means moving.

Who needs ambulatory ECG Holter monitoring? 

If you’ve got abnormal fluttering, skipping beats, dizziness or pains in your chest, and a routine Electrocardiogram (ECG) hasn’t identified a problem, a 24 hour ambulatory ECG Holter monitor test is recommended. These could be symptoms of Atrial Flutter or Atrial Fibrillation. Don’t worry if you’re diagnosed – our cardiologist specialists will create a personalised treatment plan to get you feeling better quickly.


What happens during a Holter monitor test?

The Holter monitor is the size of a mobile phone and attaches to your chest via three leads. Please note the following points.

  • The monitor sits in your pocket or is hung around your neck. 
  • You will be asked to keep a diary of any symptoms you experience during the recording period. 
  • The recording is designed to sample your active daily living, so you will be encouraged to go about your normal routine. It can be removed to shower, and you will be shown how to put it back on.



Results – what do they mean?

The Holter monitor records all of your heart beats in every 24 hours, over 115,000 if your average rate is 80 bpm. It takes a little while to go through this data to establish if the rhythm is normal, but a report will be produced as quickly as possible, and your cardiologist specialist will explain the findings to you.


What are the next steps?

If you are diagnosed with a cardiac condition, we will create a personalised treatment plan to either provide a cure, or relieve your symptoms and restore your quality of life.

Worried about palpitations?

If you have symptoms of palpitations, (also known as an arrhythmia), we recommend a longer term ECG monitor, such as a 24 Hour Holter, 48 Hour Holter or 7-day event recorder. These could help rule out other conditions, such as Atrial Flutter and Atrial Fibrillation
