If your symptoms come and go — palpitations, skipped beats, chest fluttering, dizziness, or “it happens at night / after coffee / during stress” — a Holter monitor is designed for exactly that problem: capturing the rhythm when real life happens.
If symptoms are severe (collapse, severe chest pain, severe breathlessness at rest, stroke symptoms), treat this as urgent and seek emergency care first.
A Holter monitor is ideal when the main problem is timing: your symptoms don’t reliably happen during a short clinic ECG. Holter monitoring increases the chance of capturing an episode, which is what turns worry into a specific plan.
If episodes happen in the evening, during stress, after caffeine, or randomly, a longer rhythm recording is usually more useful than repeating short ECGs.
A Holter can show if symptoms line up with rhythm changes (or if the rhythm stays normal during symptoms).
Capturing your rhythm in normal life can be more reassuring than a single normal clinic trace — because it answers the real question: what happens outside the clinic?
A normal ECG can be accurate — it may just mean the rhythm was normal at that moment. Holter monitoring is the typical next step for intermittent episodes.

Holter monitoring records the heart’s electrical activity continuously. The value is the timeline: what happens at the exact time you feel the symptom.
If your worry is valves, pumping function, or a murmur, Holter cannot answer that. That’s where an ultrasound echo fits: What is an ultrasound echo?
The aim is to make recording simple and low-stress: fit the monitor, explain what to do, then let you live normally while it records.
| Step | What happens |
|---|---|
| 1) Fit | Electrodes are placed on the chest and connected to a small recorder. We check signal quality before you leave. |
| 2) Record | You continue your day. We’ll explain practical points (clothing, showering, exercise guidance) for your recording period. |
| 3) Diary | You note symptoms with approximate times (e.g., “fluttering at 14:20”). This is what allows correlation analysis. |
| 4) Return | You return the device. We process the recording and interpret findings in context of your symptom diary. |
Preparation tip: avoid heavy moisturisers on the chest on the day (they reduce electrode adhesion). If you have previous ECGs or referral letters, bring them.
The best recording duration depends on how often symptoms occur. If symptoms happen daily, shorter monitoring can be enough. If they happen weekly or less, longer monitoring is often more efficient. If you want a quick decision first, compare: Echo vs ECG (and then choose ECG vs Holter based on symptom frequency).
Patients usually want one thing: the shortest path to certainty. Use this decision block to avoid booking the wrong test first.
Best when symptoms are happening now or you want a baseline rhythm check. ECG page: ECG test.
Best when episodes come and go. Holter is designed to catch “real life” rhythms and link them to symptoms via timing.
