These monitors are particularly useful for investigating symptoms that occur intermittently, such as palpitations, dizziness, blackouts or unexplained episodes of rapid heart rate.
Types of ECG Monitor
Depending on your symptoms and how frequently they occur, your cardiologist may recommend:
48-Hour Holter Monitor
A portable monitor worn continuously for 24 hours, recording every heartbeat during the monitoring period.
Extended ECG Monitoring
For symptoms that occur less frequently, longer-term monitoring may be recommended, ranging from several days to two weeks or more.
Event Recorders
These devices can be activated when symptoms occur, helping to capture and correlate symptoms with your heart rhythm.
What Happens During Monitoring?
Small adhesive electrodes are attached to your chest and connected to a lightweight recording device that can be worn discreetly under clothing.
You will be encouraged to continue your normal daily activities and record any symptoms in a diary. This information helps your cardiologist compare symptoms with the recorded heart rhythm.
Why Might I Need ECG Monitoring?
ECG monitoring can help investigate:
- Palpitations
- Irregular heartbeats
- Dizziness
- Blackouts or fainting episodes
- Episodes of rapid heart rate
- Suspected arrhythmias
Preparing for Your Appointment
No special preparation is required. Your cardiac physiologist will explain how to wear the monitor and provide guidance on daily activities during the monitoring period.
Results and Follow-Up
Once the monitor is returned, the recordings are analysed by specialist cardiac staff and reviewed by your cardiologist. The findings will be discussed with you along with any recommendations for further investigation or treatment.
