About Holter Monitoring
When a standard ECG isn’t enough
A standard ECG captures only a few seconds of your heart rhythm. Many important rhythm disturbances are intermittent, which means they may not appear during a short clinic test.
Holter monitoring solves this by recording your heart activity continuously while you go about normal daily life, helping identify patterns and correlate symptoms with ECG findings.
- Continuous ambulatory ECG monitoring
- Free ECG included with all packages
- Useful for palpitations, dizziness, and blackouts
- Captures intermittent rhythm disturbances
- Available as 3-day, 5-day, or 7-day monitoring
Why Holter Monitoring
How Holter monitoring solves the problem
Extended ECG monitoring helps uncover rhythm problems, symptom triggers, treatment response, and intermittent events that standard testing may miss.
Capture intermittent events
Monitor over longer periods to increase the chance of recording palpitations, arrhythmias, or symptom episodes when they actually happen.
Identify rhythm patterns
See how daily life, exercise, sleep, or stress may relate to your heart rhythm and symptom profile.
Assess treatment effectiveness
Useful for checking whether anti-arrhythmic medication or other treatment is working as intended.
Support faster private diagnosis
Direct access helps reduce delay and provides consultant-reviewed reporting to guide next steps more clearly.

Unexplained blackouts or fainting episodes
Dizziness or pre-syncope without a clear cause
Episodes of breathlessness or chest tightness without a structural explanation
Suspected paroxysmal atrial fibrillation
Known arrhythmia being monitored on treatment
Post-ablation rhythm surveillance
Assessment of slow or fast heart rhythm symptoms
Frequently Asked Questions
Common questions about Holter monitoring
Clear answers about 3-day, 5-day and 7-day ambulatory ECG monitoring, booking, preparation, daily activity and results.
Which duration should I choose: 3, 5 or 7 days?
⌄
Choose 3 days if your symptoms happen often, 5 days if they are less predictable, and 7 days if palpitations, dizziness or blackouts are occasional and may not happen during a shorter recording. If you are unsure, our team can help you choose the most suitable package.
Do I need a GP referral?
⌄
No. You can book Holter monitoring directly without a GP referral. If you already have a referral letter, previous ECG, medication list or clinic letters, please bring or send them because they help with clinical context.
What is included in every Holter package?
⌄
All packages include ambulatory ECG monitoring for the chosen duration, rhythm analysis, consultant-reviewed reporting, and a free ECG. You can also choose packages that include cardiology consultation and echocardiogram for a more complete assessment.
How quickly will I receive my results?
⌄
Results are usually available within 3–5 working days after the device is returned and the recording has been uploaded for analysis. Complex or longer recordings may occasionally take longer if additional review is needed.
Can I continue normal daily activity?
⌄
Yes. Holter monitoring is designed to record your rhythm during normal daily life. You should usually continue your usual routine, including walking, work and normal light activity, unless your clinician has advised otherwise.
Can I exercise while wearing the monitor?
⌄
Light to moderate activity is usually possible, but avoid activities that could loosen the electrodes, damage the device, or make it wet. If your symptoms are triggered by exercise, tell the team so this can be considered when reviewing your recording.
Can I shower or swim with the Holter monitor?
⌄
Most Holter devices and electrodes should not be soaked unless you are specifically told they are waterproof. Avoid swimming, baths and saunas. The team will explain exactly what is safe for the device used for your appointment.
What symptoms should I record during monitoring?
⌄
Record any palpitations, fluttering, skipped beats, dizziness, chest tightness, shortness of breath, faintness, blackouts, unusual fatigue, or symptoms that concern you. Note the time, activity and what you were doing when symptoms occurred.
What can Holter monitoring detect?
⌄
Holter monitoring can help detect intermittent arrhythmias such as atrial fibrillation, ectopic beats, tachycardias, bradycardia, pauses, heart block and rhythm changes that may not appear during a short 12-lead ECG.
Is Holter monitoring painful?
⌄
No. The test is non-invasive and painless. Small electrodes are attached to the skin and connected to a small recording device. Some people may notice mild skin irritation from adhesive electrodes.
Should I stop my medication before the test?
⌄
Do not stop any prescribed medication unless your own doctor or cardiologist has specifically advised you to do so. Bring a list of your current medications, including heart tablets, blood pressure medication and supplements.
When should I choose the package with cardiology consultation?
⌄
Choose the consultation package if you want a cardiologist to review your symptoms, explain the Holter findings, discuss risk factors and advise on next steps. It is especially useful if you have recurrent symptoms, abnormal ECG findings or a previous heart history.
When should I add an echocardiogram?
⌄
An echocardiogram is useful when structural heart assessment is also needed, for example with breathlessness, heart murmur, abnormal ECG, high blood pressure, suspected heart failure, valve disease, or family history of cardiomyopathy.
Is Holter monitoring suitable for urgent chest pain?
⌄
No. If you have current or severe chest pain, chest pain with sweating, shortness of breath, fainting, arm or jaw pain, or symptoms that feel like a heart attack, call 999 or attend A&E immediately rather than booking a private Holter test.
