Holter monitor

A portable ECG that records your heart rhythm for 24 hours to 14 days, at home and during ordinary days.

Palpitations rarely happen to order. A Holter monitor records quietly in the background, so the rhythm during your symptoms can be seen rather than guessed at.

Why it may be recommended

Palpitations, skipped beats or a racing heart
Dizziness, blackouts or near-fainting
Checking how well a rhythm treatment is working
Screening after an abnormal ECG

How to prepare

Shower before the monitor is fitted; you cannot bathe while wearing it
Wear a loose top on the day
Keep a simple diary of symptoms and times
Continue your usual medicines unless told otherwise

On the day

Small electrodes are placed on your chest and connected to a light recorder
You go home and carry on with ordinary activities
You note the time whenever you feel a symptom
The monitor is returned by post or in person when the recording ends

Your results

The recording is analysed and reported by a consultant cardiologist. Dr Sultan explains what was found, what it means for you and whether any treatment or further test is needed.

If symptoms are severe

A monitor is not for emergencies. If you have chest pain that does not settle, collapse with injury or severe breathlessness, call 999.

Questions patients ask

Frequently asked questions

If your question is not here, send a message and the practice will reply within one working day.

Can I sleep with the monitor on?

Yes. Most people sleep normally. Keep the recorder beside you rather than under the pillow.

Can I drive or work as usual?

Yes. Carry on with your normal routine so the recording reflects ordinary days — just keep the monitor dry.

What if an electrode comes loose?

Press it back on firmly and note the time in your diary. If it will not stay on, contact the practice for advice.

How soon will I get my report?

Once the monitor is returned, the recording is analysed and reported by a consultant cardiologist. The practice will tell you when to expect your results.
