Holter Monitor Test in Sharjah
Medically reviewed by Dar Al Kamal Team
What is a Holter monitor?
A Holter monitor is a lightweight, battery-powered recorder that captures the electrical activity of your heart continuously for 24 hours or longer. Small sticky electrodes on your chest connect by thin wires to the recorder, which clips to a belt or hangs from a strap. Throughout the recording, it logs every heartbeat, so the cardiologist can see how your heart rhythm behaves while you walk, work, eat and sleep.
A standard ECG records the heart for a few seconds while you lie still, which is ideal for many questions and is explained on the ECG testing page. A Holter monitor answers a different question: what the heart does across a whole day, including the moments when symptoms appear. At Dar Al Kamal Hospital, Sharjah, Holter recordings are arranged and reviewed by the cardiology team.
Who needs it
A Holter monitor suits people whose symptoms come and go, so they are easily missed by a short ECG. Common reasons for a Holter recording include:
- Palpitations, or a heartbeat that feels fast, pounding, fluttering or irregular
- Episodes of dizziness, light-headedness or fainting
- A known rhythm problem such as atrial fibrillation, to check how well the heart rate is controlled
- Checking how the heart rhythm responds to a new medicine or a change in dose
- Unexplained breathlessness or chest discomfort that appears at particular times of day
- An irregular rhythm alert from a smartwatch or fitness tracker
Smartwatch alerts are a useful prompt, and a Holter recording gives the medical-grade tracing the cardiologist needs to confirm what the watch detected. The length of the recording is chosen according to how often your symptoms occur: daily symptoms suit a shorter recording, while less frequent episodes call for a longer one.
What happens
Fitting takes around fifteen minutes. A member of the cardiology team cleans a few small areas of skin on your chest, and for men may shave small patches so the electrodes stick well. The electrodes are attached, the wires connected to the recorder, and the device switched on and checked.
You then go home and carry on with your normal routine, including work, walking, meals and sleep. Keeping to your usual day matters, because the aim is to capture your heart rhythm in real life, including whatever tends to bring on your symptoms.
You also keep a symptom diary. Each time you notice palpitations, dizziness, breathlessness or chest discomfort, you write down the time and what you were doing. Some recorders also have a button to press during a symptom. The cardiologist later matches each diary entry to the tracing at that exact moment, which is often the most informative part of the test.
At the end of the recording period you return the monitor, or remove it at home as instructed, and the data is downloaded and analysed.
Preparing for it
Shower or bathe before your appointment, because the recorder must stay dry while you wear it. Skip body lotion, oil and powder on your chest that day so the electrodes stay firmly attached.
Wear a loose, comfortable top with buttons or a front opening, which makes fitting easier and keeps the wires comfortable. Bring a list of your current medicines and continue taking them as usual unless your doctor advises otherwise. Bring a pen for your symptom diary, or plan to use your phone to note the times.
Afterwards
Once the monitor is removed, you return to normal activity straight away. Some people notice mild redness where the electrodes were, which usually settles within a day or two.
The recording is analysed and reviewed by a cardiologist, who looks at your heart rate, any pauses, any extra beats and any abnormal rhythms, and compares them with your diary. You receive the result at a follow-up appointment, where the cardiologist explains what was found and whether further tests or treatment are recommended.
Contact the hospital if the skin under the electrodes becomes blistered, very itchy or painful while you are wearing the monitor. Call emergency services or go to the emergency department straight away if you develop chest pain, fainting, severe breathlessness or a very fast heartbeat that makes you feel unwell, even while you are wearing the monitor.
Cost and insurance
Holter monitoring requested by a doctor to investigate symptoms is covered by most UAE health insurance plans, and some policies ask for pre-approval, particularly for longer recordings. The consultation to discuss the results is usually billed separately. Dar Al Kamal Hospital, Sharjah can help you confirm your cover on 06 599 7777.

Frequently asked questions
What are the limitations and risks of a Holter monitor?
A Holter monitor only records what happens while you are wearing it, so if your symptoms are rare they may not occur during the recording, and a normal result during a symptom-free recording does not rule out an intermittent rhythm problem. In that case a longer recording or an event recorder may be needed. The test itself carries no risk beyond mild skin irritation from the electrodes.
Can I shower while wearing a Holter monitor?
You should not shower, bathe or swim while wearing a Holter monitor unless you are told your device is water-resistant, because water can damage the recorder and loosen the electrodes. Shower before your fitting and again after the monitor is removed.
Why do I need to keep a symptom diary?
A symptom diary lets the cardiologist match each symptom you felt to the heart rhythm recorded at that exact time. Noting the time and what you were doing makes the Holter result far more useful than the recording alone.
Can I exercise while wearing a Holter monitor?
You can usually carry on with your normal daily activity, including walking and light exercise, while wearing a Holter monitor, because the aim is to record your heart during everyday life. Avoid activity that makes you sweat heavily or would get the recorder wet, and note any exercise in your diary.
My smartwatch says I have an irregular rhythm. Do I need a Holter monitor?
A smartwatch rhythm alert is a good reason to see a cardiologist, who may recommend a Holter monitor to confirm what the watch detected on a medical-grade recording. The watch reading alone is not enough to diagnose a rhythm problem or guide treatment.
How long will I wear the Holter monitor?
A Holter monitor is usually worn for 24 hours or longer, and the cardiologist chooses the length based on how often your symptoms occur. Less frequent symptoms need a longer recording to have a good chance of capturing an episode.
Is a Holter monitor test covered by insurance?
Most UAE insurance plans cover a Holter monitor test when a doctor requests it to investigate symptoms, although some policies require pre-approval, particularly for longer recordings. Confirm your cover with Dar Al Kamal Hospital, Sharjah on 06 599 7777.
