perimenopause heart palpitations

By Sophora Health Editorial Team · Medically reviewed · Published July 2026 · Last reviewed July 2026

It happens while you are sitting still. Watching television, lying in bed, standing at the sink. A flutter, a hard thud, a sense that your heart skipped and then caught up with a jolt. Sometimes it races for a few seconds. Sometimes it feels like it stops entirely before restarting.

Your first thought is rarely calm. Your first thought is usually: is something wrong with my heart. You are in your 40s, and this is the first time you have ever felt this.

Heart palpitations are one of the most under-discussed symptoms of perimenopause, and one of the most alarming to experience without an explanation. Up to 40 percent of perimenopausal women experience them, rising to around 50 percent after menopause.

Most of the time, they are hormonal. This article covers the mechanism, what helps, and exactly which symptoms mean you should seek medical evaluation without delay.

Why perimenopause causes heart palpitations

Estrogen helps keep the heart’s rhythm steady and supports the nervous system that automatically controls heart rate, blood pressure, and breathing.

During perimenopause, estrogen levels can rise and fall unpredictably. These fluctuations may make the heart more sensitive, contributing to sensations such as racing, fluttering, or skipped beats.

Estrogen also helps balance the two sides of the autonomic nervous system: the sympathetic system, which drives the fight-or-flight response, and the parasympathetic system, which supports rest and recovery.

As estrogen declines, this balance can shift, making the body more sensitive to adrenaline. Things that once caused little reaction, such as stress, strong coffee, or standing up quickly, may suddenly trigger noticeable palpitations.

Declining progesterone may add to this sensitivity, making palpitations more likely after common triggers such as caffeine, alcohol, stress, and poor sleep. A 2025 study identified heart palpitations as one of eight symptoms significantly associated with the perimenopausal transition.

Stress hormones can make the problem worse. Adrenaline can trigger a sudden racing or fluttering heartbeat, while persistently high cortisol may keep the nervous system more activated.

Because hormonal changes and disrupted sleep can already increase stress during perimenopause, this can create a cycle in which the body becomes more reactive and palpitations occur more often.

What perimenopausal palpitations tend to feel like

A flutter, thud, or racing sensation lasting a few seconds to a few minutes
Occurring at rest, not just during exertion or stress
Often accompanied by or following a hot flash
Common at night, sometimes waking you from sleep
Triggered or worsened by caffeine, alcohol, poor sleep, or acute stress
No chest pain, no fainting, no breathlessness alongside it

When palpitations need medical evaluation

Most palpitations in perimenopause are hormonal and benign. But palpitations can also signal an underlying cardiac condition, and hormonal palpitations can feel identical to ones that need investigation. Any new or worsening course of palpitations deserves medical evaluation, particularly the first time you experience them.

Seek medical care immediately if palpitations come with:

Chest pain or pressure
Shortness of breath
Dizziness, lightheadedness, or fainting
A palpitation episode lasting more than a few minutes without settling
A very fast, sustained heart rate that does not resolve

Beyond those emergency signs, book a routine appointment if this is your first time, palpitations are more frequent, or you have a family history of heart disease. A doctor can perform an ECG, blood tests including thyroid function, and if needed a longer-term heart rhythm monitor. Overactive thyroid also causes palpitations and is more common in perimenopause. This is not something to self-diagnose without a baseline check, even though hormonal causes are most likely for someone in their 40s with no other cardiac symptoms.

What actually helps

Reduce the known triggers

Caffeine, alcohol, and poor sleep all lower the threshold for palpitations by increasing sympathetic nervous system activity. Reducing caffeine, particularly in the afternoon and evening, and moderating alcohol intake are the two changes most likely to produce a noticeable reduction in frequency. Addressing sleep disruption, covered in detail in the insomnia article, reduces the cortisol burden that keeps the nervous system chronically activated.

Breathwork to interrupt the acute event

Slow, deep breathing directly stimulates the vagus nerve, the primary driver of parasympathetic activity, which counteracts the sympathetic activation causing the palpitation. A simple technique: inhale for four counts, hold for four, exhale for six to eight counts, repeated for one to two minutes. This does not prevent palpitations but can shorten an episode and reduce the anxiety response that follows, which itself can trigger a second wave of adrenaline.

Address hot flashes directly

Because hot flashes trigger an adrenaline surge that directly raises heart rate, reducing the frequency and severity of hot flashes reduces one of the most common palpitation triggers. The approaches covered in the hot flushes article, including layered clothing, trigger identification, and hormonal treatment where appropriate, address palpitations indirectly by addressing this upstream trigger.

HRT to stabilise the underlying rhythm

Because the mechanism traces back to estrogen’s role in cardiac electrical stability, hormone therapy that stabilises estrogen levels addresses the cause rather than the symptom. For women with significant palpitations, HRT is a well-documented option worth discussing, particularly when palpitations occur alongside other perimenopause symptoms. HRT is not appropriate for everyone, particularly those with certain cancer histories or clotting disorders, and current guidance favours the lowest effective dose for symptom control. This is a conversation for a doctor who understands both perimenopause and your individual cardiac risk profile.

Beta-blockers for frequent, disruptive episodes

For women whose palpitations are frequent enough to significantly affect quality of life, beta-blockers reduce the heart’s sensitivity to adrenaline and can meaningfully reduce episode frequency. This is a prescription decision made after cardiac causes have been excluded, and is typically considered when lifestyle changes and hormonal approaches have not been sufficient alone.

“The flutter in your chest is frightening precisely because your heart is not something you want to guess about. Getting it checked once, and understanding the mechanism after, replaces fear with clarity.”

Questions you are probably asking

Is it normal to get heart palpitations in perimenopause?

Yes. Heart palpitations are common during perimenopause and are usually harmless. Hormonal changes, particularly changing estrogen levels, can affect heart rhythm and the nervous system. However, new palpitations should still be checked by a healthcare professional, even if perimenopause is the most likely cause.

Why do my palpitations happen mostly at night?

Palpitations at night are common during perimenopause. They may be linked to hot flashes, disrupted sleep, stress, or sleep apnoea. If you regularly wake up with a racing heart, tell your doctor. They may recommend checking your heart and, in some cases, assessing your sleep.

How do I know if my palpitations are hormonal or something more serious?

It can be difficult to tell from symptoms alone because hormonal palpitations can feel similar to an abnormal heart rhythm. Brief episodes that settle on their own and occur with triggers such as hot flashes, stress, or caffeine may be reassuring. However, palpitations accompanied by chest pain, fainting, or significant shortness of breath need urgent medical attention. If your palpitations are new, a medical assessment can help identify the cause.

Will palpitations stop after menopause?

For many women, palpitations improve once hormone levels become more stable after menopause. For others, they may continue, especially when other heart or health factors are involved. Persistent palpitations should be discussed with a healthcare professional rather than assumed to be hormonal.

Can anxiety cause the same feeling as hormonal palpitations?

Yes. Anxiety and hormonal changes can both activate the body’s stress response, releasing adrenaline and causing a racing, pounding, or fluttering heartbeat. The two can also occur together during perimenopause. This does not mean palpitations should automatically be dismissed as anxiety. A healthcare professional can help determine what is causing them.

In summary

You now know: Heart palpitations in perimenopause are driven by estrogen’s declining stabilising effect on cardiac electrical activity. Falling progesterone and elevated cortisol compound it. Up to 40 percent of perimenopausal women experience them, and they are usually benign.

One thing to do: If this is the first time you have experienced palpitations, book a baseline medical evaluation including an ECG and thyroid function tests. This is true even though perimenopause is the most likely explanation, because a baseline check replaces uncertainty with confirmed clarity.

Hold onto this: Chest pain, fainting, or breathlessness alongside palpitations always warrant immediate medical attention. Everything else in this article assumes those signs are absent. If they are present, seek care straight away rather than reading further.
