Holter Monitoring – 24–48 Hour Heart Rhythm Recording in Australia
Holter monitoring records your heart’s electrical activity over 24–48 hours (or longer if needed) while you go about your normal activities. It helps capture irregular heartbeats or arrhythmias that may not show up on a brief ECG.
Who it's for
Holter monitoring is for patients with intermittent palpitations, dizziness, or suspected arrhythmias that are not captured on a single ECG. It is also used to assess heart rate control in conditions such as atrial fibrillation or to check pacemaker function.
What to expect
Small sticky electrodes are placed on your chest and connected to a small recorder that you wear on your belt or in your pocket. You can shower with a waterproof cover or remove it briefly as instructed. You will keep a simple diary of symptoms and activities. After the monitoring period, you return the device and we analyse the recording and discuss the results with you.
When to see a cardiologist
Your cardiologist or GP may recommend Holter monitoring if you have symptoms that suggest an arrhythmia but your ECG was normal, or to assess how well your rhythm or rate is controlled over a typical day.
