Continuous monitoring of your heart rhythm over time.
Expert cardiology care with a personal approach.
A Holter monitor is a portable ECG device that records your heart’s electrical activity continuously over 24 to 48 hours.
It is used to detect irregular heart rhythms that may not appear during a standard in-clinic ECG.
This test is especially helpful when symptoms come and go throughout the day or night.
During your appointment:
A small portable monitor is fitted to your body
Electrodes are placed on your chest to record heart rhythm
You will wear the monitor during your usual daily activities
You may be asked to keep a diary of symptoms and activities
Once the recording period is complete, the monitor is returned for analysis.
Your cardiologist will review the results and provide a report to your referring doctor.
You may be referred for a cardiology consultation if you experience:
Palpitations
Dizziness
Fainting or near-fainting episodes
Irregular heartbeat
Suspected arrhythmias
It may also be used to assess ongoing symptoms, investigate abnormal ECG results, or monitor known rhythm conditions.

A 24-hour Holter Monitor is a small, wearable device that continuously records your heart’s electrical activity over a full day. It provides a detailed picture of how your heart functions during normal daily activities and sleep.
Your doctor may recommend a Holter Monitor if you experience symptoms such as palpitations, dizziness, or fainting spells, or if there are irregularities seen on a standard ECG. It helps identify heart rhythm problems that may not appear during a short in-clinic test.
Several small electrodes are placed on your chest and connected to a portable recorder worn on your belt or shoulder strap. You’ll be asked to continue your normal activities while wearing the device and to record any symptoms in a diary for comparison with the data collected.
You will not be able to shower, bathe, or swim during the monitoring period, as the device is not waterproof. Light activity is fine, but avoid excessive sweating or vigorous exercise that could loosen the electrodes.
You’ll return the monitor to our clinic, where the data will be downloaded and analysed by a cardiologist. Your referring doctor will then discuss the results with you and determine any next steps in your care.
