Perimenopause Heart Palpitations: What to Log and When to Call 999
Fluttering, thumping or a racing heart in midlife. The NHS lists menopause among the causes — and also the symptoms that mean stop tracking and get help now.
The Short Answer
The NHS palpitations guidance is reassuring and specific at the same time: palpitations are common and not usually a sign of anything serious, they can sometimes be a sign you are going through the menopause, and they can also be caused by iron deficiency anaemia, an overactive thyroid, a heart rhythm problem or other heart conditions.
That combination is exactly why this symptom deserves a written log rather than either panic or dismissal. What a clinician needs is not your interpretation — it is what the beat felt like, how long it lasted, what you were doing, and what else was happening at the time.
What to Record When It Happens
This is a symptom you log in the moment or shortly after, not in a nightly summary. Six fields, thirty seconds.
- What it felt like. Racing, irregular with skipped or extra beats, pounding, or fluttering — the NHS uses these four descriptions and so should you.
- How long. Seconds, minutes, or longer. An estimate is fine.
- Where you felt it. Chest, neck or throat.
- What you were doing. Resting, standing up, exercising, lying in bed, mid-argument, waking from sleep.
- Anything with it. Chest pain, breathlessness, faintness, sweating, a hot flash, anxiety, nausea.
- The 24-hour context. Sleep, alcohol, caffeine, nicotine, a new medicine or dose change, illness, hard exercise, and where you are in your cycle.
The Patterns That Change the Conversation
| Pattern in your log | Why it matters | What to do |
|---|---|---|
| Only ever at rest in the evening, seconds long, nothing else with it | The most commonly reported and least alarming shape | Still mention it; note caffeine, alcohol and sleep alongside |
| Clustered on poor-sleep or high-alcohol days | Points at modifiable triggers the NHS names directly | Try changing one, keep logging, and report the result |
| Alongside heavy periods and fatigue | Iron deficiency anaemia is on the NHS cause list | Ask specifically whether a blood test is appropriate |
| Alongside weight change, heat intolerance or tremor | An overactive thyroid is on the NHS cause list | Mention the cluster, not just the palpitations |
| Lasting longer than a few minutes, or becoming more frequent | An NHS threshold for seeing a GP | Book an appointment |
| With chest pain, breathlessness or faintness | An NHS threshold for emergency care | Call 999 — do not log and wait |
What You Can Reasonably Change
The NHS notes that avoiding triggers such as stress, smoking, caffeine and alcohol can help when palpitations are not caused by a health condition. That is a short list, and it is worth working through it one item at a time so you can tell which one mattered.
- Move caffeine earlier, or cut the second cup, for two weeks and compare.
- Note alcohol units and which nights, then look at the following 24 hours in your log.
- Protect sleep — lack of sleep is explicitly on the NHS cause list, and it is often the easiest thing to see in a record.
- Treat anxiety as a real contributor rather than a dismissal. Stress and anxiety are on the same list, and both are treatable.
- Check medicine leaflets, and raise anything new with a pharmacist or GP rather than stopping it yourself.
If anxiety is a large part of the picture, our post on perimenopause mental health covers it properly, and perimenopause insomnia covers the sleep side.
How Perim Helps Here
Palpitations are the classic symptom that vanishes the moment you sit in a clinic room. A dated record of a dozen episodes — what each felt like, how long, and what surrounded it — is far more useful than trying to describe the worst one from memory, and it is exactly the input an ECG or referral decision benefits from.
Perim is a notebook, not a monitor: it does not measure your heart and it cannot tell you whether a rhythm is normal. See what it tracks, and take the record to a qualified health professional.
Frequently Asked Questions
Can perimenopause cause heart palpitations?
The NHS says palpitations can sometimes be a sign you are going through the menopause, and palpitations also appear on its perimenopause symptom list. It equally lists strenuous exercise, lack of sleep, stress and anxiety, medicines, alcohol, caffeine and nicotine, iron deficiency anaemia, an overactive thyroid and heart rhythm problems as causes.
What do menopause palpitations feel like?
The NHS describes palpitations as a heartbeat that feels racing or very fast, irregular with skipped or extra beats, pounding or thumping, or fluttering — felt in the chest, neck or throat. They can last seconds, minutes or longer.
When should I call 999 for palpitations?
The NHS says to call 999 or go to A&E if you currently have palpitations that do not go away, or if palpitations come with chest pain, shortness of breath, or feeling faint or fainting. Do not drive yourself.
When should I see a GP about palpitations?
See a GP if you feel well but the palpitations keep coming back or are happening more often, last longer than a few minutes, or if you have a heart condition or a family history of heart problems.
Why do palpitations happen at night?
Lying still and quiet makes a heartbeat easier to notice, and night is also when alcohol is wearing off, a night sweat may be passing and anxiety often peaks. That does not make night palpitations less worth logging — the time of day is useful information.
What will a doctor do about palpitations?
The NHS says treatment depends on the cause and often none is needed. You may be offered an ECG to look at the electrical signals from your heart, and may be referred to a cardiologist for further tests. A written log of what you felt and when helps that assessment.
