menopause and heart palpitations, flutters and a racing heart

Your heart thuds, skips, or takes off like you have just run for a bus, except you are sitting on the sofa. Then it stops. And you spend the next twenty minutes googling whether you are having a heart attack. If that is you, you are in very ordinary company, and there is more real research on this than you would guess.

Can menopause cause heart palpitations?

Yes, and they are far more common than most women realize. A systematic review of five studies across five countries found palpitations reported by 20.1 to 42.0 percent of perimenopausal women and 15.7 to 54.1 percent of postmenopausal women (Carpenter JS et al, Curr Obstet Gynecol Rep 2021, DOI 10.1007/s13669-020-00302-z).

The largest picture comes from SWAN, which tracked 3,276 women and found three distinct patterns. Around 16 percent had a high probability of palpitations that peaked in perimenopause and early postmenopause then faded. Another 34 percent had a moderate probability following the same shape. The remaining half had consistently low probability (Carpenter JS et al, Menopause 2023, PMID 36256921).

So roughly half of women get through the transition without this. The other half do not, and it clusters around exactly the years when everything else is changing.

Why do I get heart flutters in perimenopause?

Estrogen influences the autonomic nervous system, the part that sets your heart rate without you thinking about it. When estrogen swings, that regulation gets noisier. Add the things that reliably ride along with perimenopause, and you have a system primed to produce extra beats and to notice them.

In the SWAN analysis, the women in the high palpitation group were more likely to be in early perimenopause, to have vasomotor symptoms, poorer overall health, higher depressive symptoms, higher perceived stress, more sleep problems and higher blood pressure. It is rarely one thing.

Worth saying plainly: a lot of what women experience as new palpitations is a normal extra beat that was always happening and is now being noticed, because sleep is worse and the nervous system is running hot.

Are menopause palpitations dangerous?

This is the question underneath all the others, so here is the most reassuring finding in this whole area.

The SWAN researchers also looked at 1,559 of those women for subclinical cardiovascular disease, measuring carotid artery thickness, arterial plaque and arterial stiffness. Palpitation patterns were not related to any of them (Carpenter JS et al, Menopause 2023, PMID 36256921). Women who reported palpitations across the transition did not show more early cardiovascular disease than women who did not.

That is one good study, not a guarantee about you personally, and it does not remove the need to get new palpitations checked once. But it is real evidence against the assumption that palpitations in midlife mean your heart is in trouble.

There is a second finding worth knowing. In interviews with 14 women, researchers found many did not report palpitations to their doctor at all, or had them dismissed when they did, and set unreasonably high thresholds before seeking care (Carpenter JS et al, Menopause 2023, PMID 37643379). Being reassured is not the same as being ignored. Get it looked at once, properly, and then you have your answer.

Do hot flashes cause heart palpitations?

They travel together, and the mechanism gives a clue why. During a hot flash, heart rate rises by 10 to 20 beats per minute above baseline, plasma epinephrine rises by around 150 percent, and finger blood flow increases roughly thirtyfold (Kronenberg F et al, Maturitas 1984, PMID 6472126). That is a whole body surge, not just a feeling of heat.

A cross sectional study of 394 women aged 40 to 59 found that moderate to severe palpitations were independently associated with vasomotor symptom score, and notably were not associated with age, menopausal status, resting heart rate, arrhythmia, caffeine or alcohol (Enomoto H et al, Menopause 2021, PMID 34033601).

The honest framing is that they occur together often, and a shared autonomic mechanism is the leading hypothesis. Calling it proven would be overstating it.

Does HRT cause heart palpitations or help them?

Both claims circulate and neither is well supported. A systematic review of 37 studies on treatments for menopausal palpitations found no Level I evidence at all and concluded that no therapy can be fully recommended, with only some hormonal agents such as estradiol recommended cautiously on the basis of some positive findings (Sheng Y et al, Climacteric 2022, PMID 34346265).

On the other side of the question, palpitations appeared as an adverse effect in only 11 percent of those articles, and in the hormonal arms exactly one participant withdrew because of palpitations from transdermal estradiol.

What that means for you: hormone therapy is not a reliable fix for palpitations and is not a common cause of them either. If you started HRT and palpitations began soon after, tell your prescriber rather than stopping on your own, because dose and delivery route can be adjusted.

Can anxiety cause heart palpitations in menopause?

The evidence here is genuinely mixed, which is not what most articles will tell you.

In that study of 394 women, each point on the anxiety scale raised the odds of moderate to severe palpitations by around 19 percent (Enomoto H et al, Menopause 2021, PMID 34033601). Pooled data from 759 women in the MsFLASH trials found palpitation distress higher alongside worse insomnia, depressive symptoms and perceived stress (Carpenter JS et al, J Womens Health 2021, PMID 33217253).

But a scoping review of 84 articles classed anxiety as an unclear correlate because fewer than three studies had tested it properly, and a 2025 pilot study using two to four weeks of ambulatory ECG found palpitation reporting was not related to anxiety at all (Carpenter JS et al, Menopause 2025, PMID 40554632).

The fair conclusion is that anxiety and palpitations are strongly associated in midlife women, they feed each other, and nobody has demonstrated which one starts it. Being told "it is just anxiety" without an examination is not an answer.

Does magnesium help heart palpitations?

People search this a lot, so we are going to answer it honestly rather than conveniently.

There is no trial of magnesium supplementation for palpitations in menopausal or otherwise healthy women. The systematic review of every treatment ever studied against menopausal palpitations does not mention magnesium once. The positive magnesium trials that circulate online were done in cardiology patients with hundreds of documented abnormal beats on a 24 hour monitor, which is a completely different population from a healthy woman noticing flutters in perimenopause.

Magnesium has established roles in normal muscle and nerve function and in sleep, and better sleep is genuinely relevant here because sleep problems tracked with palpitations in the SWAN data. But we are not going to tell you magnesium settles palpitations, because that claim has never been tested in women like you.

How to stop hormonal heart palpitations naturally

Nothing here is a treatment for a heart rhythm problem. These are the ordinary levers that tend to reduce how often the surges happen and how alarming they feel.

• Keep a two week log. Time of day, what you had eaten and drunk, how you slept, what you were doing. Patterns show up fast and it makes your doctor's appointment far more productive.
• Halve the caffeine before you cut it. Abrupt withdrawal produces its own symptoms. Note that the study above did not find a caffeine association, so this is worth testing on yourself rather than assuming.
• Look at alcohol seriously. Alcohol is a well documented trigger for palpitations and it fragments the second half of the night, which loads the following day.
• Eat before you get shaky. A blood sugar dip produces an adrenaline response, and adrenaline produces exactly this sensation. Protein at each meal, and do not skip breakfast.
• Slow the out breath. When one starts, breathe in for four and out for six or eight for two minutes. A longer exhale engages the parasympathetic side of the nervous system. It is not a placebo and it is free.
• Treat the sleep, not just the day. Sleep problems tracked with the high palpitation group in SWAN. This is one of the few modifiable factors with real data behind it.
• Get your thyroid and iron checked. An overactive thyroid and anemia both produce palpitations and both are simple blood tests.

When should you see a doctor about palpitations?

Call emergency services immediately if palpitations come with chest pain or pressure, severe shortness of breath, nausea, sweating, or a feeling that you are about to pass out. Those are heart attack symptoms and are not something to sit with.

Arrange an urgent appointment if you faint or nearly faint, if the palpitations are sustained rather than a few seconds, if they come with dizziness or breathlessness, or if you have a personal or family history of heart disease, arrhythmia or sudden cardiac death.

Book a routine appointment for any new palpitations, even mild ones, at least once. Ask for a thyroid panel, a full blood count including ferritin, an ECG, and a discussion about whether a longer monitor is worth wearing. Getting a clear answer once is worth far more than years of quiet worry.

Frequently Asked Questions

Why do I get heart palpitations at night in perimenopause?

Lying still removes the distractions that mask a normal extra beat, so palpitations become far easier to notice. Night sweats, alcohol earlier in the evening and a late meal all add to it. If they consistently wake you from sleep rather than occurring while you are lying awake, mention that specifically to your doctor.

Can low estrogen cause a racing heart?

Estrogen influences autonomic regulation of heart rate, so fluctuating levels plausibly contribute. Palpitation rates in SWAN peaked in perimenopause and early postmenopause, which fits that picture. It is an association rather than a proven cause, and a racing heart still deserves a thyroid check.

How long do menopause palpitations last?

In the SWAN trajectory data, the groups with high and moderate probability of palpitations both peaked around perimenopause and early postmenopause and diminished in late postmenopause. Individual episodes usually last seconds to a couple of minutes.

Are palpitations a sign of heart disease in menopausal women?

In the SWAN analysis of 1,559 women, palpitation patterns were not related to carotid artery thickness, arterial plaque or arterial stiffness. That is reassuring evidence, but it does not replace an individual assessment, and any new palpitations should be checked once by a doctor.
