Heart Palpitations and Menopause: Understanding the Connection

Yes, menopause can cause heart palpitations, and for most women they are harmless. They tend to arrive with hot flashes, at night, or in the middle of a wave of anxiety, and they ease as hormones settle or when hot flashes are treated. But a racing heart deserves attention at any age, and a few patterns need urgent care. This page explains why palpitations happen in perimenopause and menopause, whether hormone therapy causes or calms them, exactly when to worry, and what a doctor will check.

Why menopause causes palpitations

The heart’s rate and rhythm are set by the autonomic nervous system, the automatic one that also controls temperature, sweating and the fight-or-flight response. Estrogen quietly steadies that system. As estrogen falls and, in perimenopause, swings up and down, the balance shifts toward the “alert” side: more adrenaline-type signalling, a higher resting heart rate for some women, and a heart that reacts more sharply to triggers.

That is why palpitations and hot flashes travel together. A hot flash is the same system misfiring on temperature, and heart rate typically rises by around 7 to 15 beats a minute during one. At night the pattern is sharper still: a night sweat jolts you awake, the heart is already pounding, and the surge of alarm that follows keeps it there. Poor sleep and anxiety, both common in the transition, lower the threshold further.

What they feel like

Women describe a sudden awareness of the heartbeat: racing, pounding, fluttering, a skipped beat followed by a thud, or a brief run of fast beats. Episodes usually last seconds to a couple of minutes. They are commonest:

• during or just before a hot flash
• lying in bed, especially after waking hot
• after caffeine, alcohol or a large meal
• during stressful moments, or out of nowhere in a calm one, which is the part that frightens people

Palpitations that come with a heat wave, pass within minutes and leave you otherwise well are the menopausal pattern.

Perimenopause vs after menopause

In perimenopause, when estrogen is swinging rather than simply low, palpitations are often at their most frequent and most unpredictable, and they track the bad hormone weeks the same way mood and sleep do. After menopause, levels are low but steady, and for many women palpitations fade along with hot flashes over a few years. Palpitations that start or worsen well after menopause, with no hot flashes attached, are less likely to be hormonal and more worth investigating. Our perimenopause vs menopause guide explains the stages.

Does HRT cause heart palpitations?

For most women, hormone therapy reduces palpitations, because it reduces the hot flashes and night sweats they ride on and restores sleep. If you’ve started hormone therapy and palpitations have improved, that is the expected direction.

Palpitations can appear on treatment in a few situations:

• The dose is too high. Too much estrogen can produce a jittery, overstimulated feeling with a faster heartbeat, along with breast tenderness and headaches; see our page on estrogen overload. The fix is a lower dose, not stopping.
• A change in progestogen. Some women notice palpitations or anxiety on particular progestogens and do better on micronised progesterone, or with a different timing.
• The first weeks. Hormones fluctuate before levels settle; palpitations in the first two or three weeks often resolve on their own.

Hormone therapy at the usual doses, started under 60 or within ten years of menopause, is not associated with dangerous rhythm problems in healthy women. The wider question of hormones and heart risk, including the FDA’s 2025 label changes, is covered on our heart risk and hormone therapy page. Whatever is happening, palpitations on HRT are a reason to message your prescriber, not to stop abruptly.

When to worry about palpitations

Go to an emergency department, or call 911, if palpitations come with:

• chest pain, pressure or tightness, or pain spreading to the arm, jaw or back
• fainting, near-fainting or sudden severe dizziness
• severe shortness of breath
• a very fast pulse (roughly 150 or more at rest) or an irregular, chaotic pulse that doesn’t settle within a few minutes
• confusion, or weakness or numbness on one side

See a doctor soon, without panic, if:

• palpitations are new after 50 and happening most days
• they happen during exercise rather than at rest
• episodes last longer than a few minutes or are getting more frequent
• you have known heart disease, high blood pressure, diabetes or a thyroid problem
• a close relative died suddenly or has a heart rhythm condition
• you also have unexplained weight loss, heat intolerance, tremor, or very heavy periods (thyroid and anaemia, below)

Everything else, meaning brief episodes attached to hot flashes in an otherwise well woman, can be raised at a routine visit.

What else causes palpitations at midlife

Menopause is the most common explanation but not the only one, and some of these are easy to miss because their symptoms overlap:

Cause	Clue
Overactive thyroid	Heat intolerance, weight loss, tremor, anxiety, loose bowels; a simple blood test
Anaemia from heavy perimenopausal bleeding	Fatigue, breathlessness on stairs, pale skin; blood count and iron
Caffeine, alcohol, nicotine, decongestants, some asthma inhalers, stimulant medications, high-dose thyroid medication	Timing after the exposure
Low potassium or magnesium, dehydration	Cramps, after illness, on diuretics
Anxiety and panic	Palpitations with a sense of dread, tingling, breathlessness, often resolving with slow breathing; real and treatable, and common in the transition
Sleep apnoea	Snoring, waking unrefreshed, morning headaches; more common after menopause
Atrial fibrillation and other arrhythmias	An irregular pulse, episodes lasting many minutes to hours; risk rises with age and AF is under-diagnosed in women
Blood pressure that has crept up	Common after menopause; check it

What a doctor will check

Expect a conversation about when the episodes happen and what accompanies them, a pulse and blood pressure check, and an ECG. Because palpitations are episodic, a normal ECG in the office doesn’t rule much out, so if episodes are frequent you may wear a monitor for a day or two (a Holter) or longer (a patch). Blood tests usually include thyroid, a blood count and electrolytes. An echocardiogram is added if the examination or ECG suggests it. In the great majority of midlife women this work-up is normal, and knowing that is itself a treatment: palpitations you’ve been told are benign are far easier to breathe through.

If you wear a smartwatch, a rhythm strip captured during an episode is genuinely useful; bring it.

What helps

1. Treat the hot flashes and the sleep. When palpitations ride on vasomotor symptoms, hormone therapy, or a non-hormonal option such as fezolinetant or a low-dose SSRI/SNRI, usually quiets them too.
2. Remove the amplifiers. Caffeine after noon, alcohol in the evening, decongestants and nicotine are the common ones. Keep hydrated; check iron if your periods are heavy.
3. Slow breathing during an episode. In for four, out for six, shoulders down, for two minutes. It won’t stop a true arrhythmia, but it shortens the adrenaline spiral that turns a ten-second flutter into a half-hour of fear. CBT for menopause teaches this and the thinking skills around it.
4. Move. Regular aerobic exercise lowers resting heart rate and anxiety; palpitations during exercise are the exception that needs checking first.
5. Get the thyroid and blood count done if you haven’t; both are cheap and both masquerade as menopause.

Getting help

Palpitations are one of the symptoms Golden Leaf’s care team hears about most, and one of the most relieved-looking when a woman learns they’re part of the same hot-flash story and that the story has a treatment. Our visits are by video, so if your episodes have red-flag features we’ll tell you plainly to be seen in person first. Otherwise, book a first visit and we’ll work through the whole pattern, heart included.
