Heart palpitations in menopause are common, and they are usually harmless. Fluctuating oestrogen, hot flushes, broken sleep and anxiety all make them more likely. A new palpitation still deserves an ECG, because menopause does not rule out an arrhythmia.
The sensation is different for everyone: a flutter, a pounding in the neck, a pause followed by a thump, or a heart that suddenly races for no reason. What matters is not how dramatic it feels but whether the rhythm is normal. This page explains why the heart behaves this way in perimenopause, how doctors separate a hormonal palpitation from an arrhythmia, and which tests actually settle the question.
Heart palpitations in menopause: why they happen:
Oestrogen does more than regulate the menstrual cycle. It influences the autonomic nervous system, the branch of the nervous system that sets heart rate and blood vessel tone, and it interacts with the pathways that let the heart respond to stress. When oestrogen swings unpredictably during perimenopause, that control becomes less steady. The result is a heart that feels more reactive: faster on standing, more noticeable at night, and more sensitive to caffeine, alcohol and a bad night's sleep.
The NHS lists a faster, slower or more noticeable heartbeat among the symptoms of menopause and perimenopause, and notes that a hot flush can itself cause palpitations, anxiety or dizziness. That link matters. A flush is a sudden surge of sympathetic activity, with a rise in heart rate and a drop in vascular resistance. If you feel your heart pound at the same moment your face and chest burn, the two are probably part of one event rather than two separate problems.
The evidence supports this picture without claiming that hormones explain every case. In the SWAN cohort, which followed thousands of midlife women across the transition, three patterns emerged: about 16% had a high probability of palpitations from perimenopause into early postmenopause, about 34% had a moderate probability, and about half stayed at a low probability throughout. Palpitations were not associated with subclinical atherosclerosis or arterial stiffness. In other words, a woman whose heart races through the transition does not automatically have early heart disease.
A 2022 scoping review of 84 studies found the most consistent correlates of menopausal palpitations were worse vasomotor symptoms, worse sleep, lower physical activity and worse quality of life. Age, body mass index and most coexisting conditions were not likely correlates. This is useful clinically: it suggests that the drivers are often the symptoms sitting alongside the palpitations, not the passage of years by itself.
Hormonal palpitations or an arrhythmia:
Most heart palpitations in menopause are not dangerous, but the whole point of assessment is to find the minority that are. The history does much of the work. A hormonal palpitation usually arrives in a context: a flush, a stressful week, too little sleep, several coffees, a glass of wine the night before. It tends to be brief, to settle when the trigger settles, and to feel different from a true sustained arrhythmia.
An arrhythmia is more likely to be abrupt: it starts without warning, at rest, and stops just as suddenly. Palpitations that begin during exercise, that come with chest pain or breathlessness, or that cause fainting are a different matter and need urgent assessment. The American Academy of Family Physicians advises a deeper cardiac evaluation when there is a personal history of cardiovascular disease, a family history of arrhythmia or sudden cardiac death, an abnormal examination, or an abnormal ECG.
| Feature | Usually hormonal | More concerning for arrhythmia |
|---|---|---|
| Onset | Gradual, with a flush or stress | Sudden, often at rest |
| Duration | Seconds to a few minutes | Minutes to hours, or ongoing |
| Triggers | Heat, sleep loss, caffeine, alcohol, stress | Exercise, none at all |
| Associated symptoms | Flushing, sweating, anxiety | Chest pain, breathlessness, fainting |
| Pattern | Comes and goes with other symptoms | Recurrent, stereotyped, increasingly frequent |
| ECG between episodes | Normal | May show an abnormality |
The table is a guide, not a diagnosis. A normal ECG between episodes does not exclude an intermittent arrhythmia, and a racing heart during a hot flush can still be an arrhythmia that happens to coincide with one. That is why the event itself, recorded on a monitor, matters more than a description of it.
There is also a middle ground that is easy to miss. A 2025 pilot study that fitted 14- to 28-day ECG patches to 15 women with palpitations and 15 without found that the palpitations group had lower heart rate variability and longer runs of atrial tachycardia. Their symptoms occurred during abnormal rhythms and during normal sinus rhythm, with normal rhythm more common at night. The authors describe this as hypothesis-generating rather than settled, but it makes an important point: the same sensation can have more than one cause, and only a recording can tell them apart.
How heart palpitations in menopause are investigated:
The first test is a resting 12-lead ECG. It is quick, painless and tells the doctor whether the heart's electrical wiring looks normal between episodes. It can reveal a long QT interval, conduction delay, signs of previous heart damage, or an unsuspected rhythm problem. A normal tracing is reassuring but not the end of the story.
If the ECG is normal and symptoms keep returning, the next step is ambulatory monitoring: a Holter for 24 to 48 hours, a patch or event recorder for a week or more, or a small device you press when symptoms start. The choice depends on how often the palpitations happen. A 24-hour monitor is useless if the episodes occur once a fortnight. Longer patches are now common for exactly this reason.
Blood tests look for the treatable causes that mimic hormonal palpitations. A full blood count can show iron deficiency anaemia, which makes the heart work harder and beat faster. Thyroid function tests can show an overactive thyroid, a classic cause of a racing heart, heat intolerance and weight loss. Electrolytes, glucose and kidney function are usually checked too. Your GP may also review medicines and supplements, since decongestants, some asthma inhalers and thyroid medicines can all provoke palpitations.
An echocardiogram is not routine for everyone. It is used when the examination finds a murmur, when there is a family history of structural heart disease, or when the ECG is abnormal. If the diagnosis remains unclear, or if you have fainted, you may be referred to a cardiologist. A cardiac event monitor or, rarely, an implantable loop recorder can then be used to catch a rhythm that only appears occasionally.
What helps hormonal palpitations:
The first step is to reduce the triggers you can control. Sleep is the most underrated. In the SWAN data, poor sleep tracked closely with palpitations, and a night of repeated waking raises sympathetic activity for the whole of the next day. Treating night sweats and sleep disruption can therefore reduce daytime palpitations, even if it does not remove them.
Caffeine, alcohol and nicotine are worth an honest audit. They do not cause an arrhythmia, but they make a sensitised heart more excitable, and many women find that two coffees are fine while four produce a flutter. Staying hydrated and avoiding large, very cold drinks can help some people. Regular moderate exercise lowers resting heart rate and improves heart rate variability; the scoping review found lower physical activity among women with more palpitations, although that does not prove cause and effect.
If vasomotor symptoms are the main driver, treating them is reasonable. A 2022 systematic review of menopausal symptom treatments and palpitations concluded that no therapy could be fully recommended for palpitations specifically, because the evidence is limited. Some hormonal agents, particularly estradiol, had positive signals and can be used with caution; other options studied, including moxonidine, atenolol, isoflavones, sage and cognitive behavioural therapy, could not be recommended on the available evidence. That does not mean they never help. It means the evidence is not strong enough to promise they will.
Does HRT help or harm the heart:
For most women who start HRT before 60 or within ten years of menopause, NICE NG23 states that coronary heart disease risk does not increase with combined or oestrogen-only HRT, and that cardiovascular mortality does not increase either. HRT is not, however, a treatment for cardiovascular prevention, and NG23 advises against offering it for that purpose.
The route of oestrogen matters. NG23 recommends considering transdermal HRT rather than oral for people at increased risk of venous thromboembolism, including those with a BMI over 30. It also notes that stroke risk is unlikely to increase with combined HRT containing transdermal oestrogen, while it does increase with combined HRT containing oral oestrogen. If you have palpitations and are considering HRT, that is a conversation to have with your clinician rather than a decision to take from a table.
What HRT may do is reduce the vasomotor symptoms that trigger palpitations. That is an indirect benefit, and it is why some women notice fewer episodes once flushes are controlled. It is not a reason to start HRT solely for palpitations.
Other causes worth ruling out:
Not every racing heart in midlife is hormonal. An overactive thyroid is more common in women and can produce palpitations, heat intolerance, tremor and weight loss. Iron deficiency anaemia causes fatigue, breathlessness and a fast heartbeat, and heavy periods during perimenopause make it more likely. Anxiety and panic attacks produce genuine physical symptoms and can coexist with a cardiac cause rather than excluding it.
Atrial fibrillation becomes more common with age, and its hallmark is an irregular, often rapid heartbeat that may come and go. It carries a stroke risk that changes management, which is why an ECG during symptoms is worth the effort. Medicines, alcohol withdrawal, dehydration and viral illness can all provoke episodes. A good clinician will keep the whole list in mind rather than assuming the menopause explains everything.
Tracking your palpitations before an appointment:
A simple diary makes the appointment far more useful. Note the date and time, what you were doing, how long it lasted, whether it started and stopped suddenly, and what else you felt: flushing, chest pain, breathlessness, dizziness or anxiety. If you have a smartwatch or a home blood pressure monitor that records an ECG, bring the tracing, but do not rely on it to rule anything out.
Record the things that might be triggers: sleep, caffeine, alcohol, stress and the point in your cycle if you still have periods. A two-week record often reveals a pattern that neither you nor your doctor could see from memory alone. It also gives the appointment a concrete starting point, which is worth more than a vague description of a racing heart.
When to see a doctor:
Call emergency services or go to an emergency department if you have palpitations that do not stop, chest pain, shortness of breath, or you feel faint or actually faint.
See a GP if palpitations keep coming back or are happening more often, if an episode lasts longer than a few minutes, if you have a known heart condition, or if you have a family history of heart problems. Also book an appointment if the palpitations start during exercise, if they interfere with sleep or work, or if you are worried. A normal ECG is reassuring, but it does not replace an assessment of the symptom that sent you there.
