Heart Palpitations During Perimenopause: When Are They Hormonal?
You're sitting quietly when suddenly your heart feels like it's racing.
Or maybe it flutters.
Skips a beat.
Pounds hard for several seconds.
Then everything seems normal again.
If you're in your 40s and your periods have started changing, you may wonder:
“Is this another perimenopause symptom?”
It could be.
Heart palpitations are reported during the menopause transition, and some women notice a rapid heartbeat alongside hot flashes. The Menopause Society
But there's an important rule:
New heart symptoms should not automatically be blamed on hormones.
Palpitations can also be associated with thyroid disorders, anemia, medications, caffeine, alcohol, stress, dehydration, or abnormal heart rhythms.
The goal isn't to panic every time your heart skips a beat.
It's to know when hormones may be contributing—and when your heart deserves further evaluation.
What Do Heart Palpitations Feel Like?
Palpitations simply mean that you become unusually aware of your heartbeat.
Women describe them in many ways:
Racing
Fluttering
Pounding
Thumping
Flip-flopping
Skipped beats
Extra beats
A sudden strong heartbeat
You may feel them in your chest, throat, or neck.
They may occur during activity, while you're sitting quietly, or even when you're lying in bed.
Most palpitations aren't dangerous, but some can reflect an abnormal heart rhythm that requires medical attention. Cleveland Clinic
Can Perimenopause Really Cause Heart Palpitations?
Yes, palpitations can occur during perimenopause and menopause.
Hormonal changes during the menopause transition are considered one possible contributor, and palpitations may begin during perimenopause and continue through menopause or early postmenopause. Cleveland Clinic
They're also recognized among menopause and perimenopause symptoms by the NHS. nhs.uk
But the relationship is more complicated than:
Low estrogen = palpitations.
Perimenopause involves fluctuating ovarian hormones rather than a smooth, predictable decline.
At the same time, women may experience changes in:
Sleep • Stress • Hot flashes • Anxiety • Caffeine tolerance • Alcohol use • Thyroid health • Iron status
Any of these can potentially influence how noticeable the heartbeat becomes.
So it's often better to think of palpitations as a symptom that can occur during perimenopause, rather than assuming that estrogen is always the direct cause.
Why Might Hormonal Changes Affect Your Heartbeat?
Estrogen interacts with multiple tissues and physiological systems, including cardiovascular and autonomic nervous-system pathways.
During perimenopause, estrogen levels can fluctuate considerably.
These changing hormonal signals may influence how the body regulates:
Heart rate
Blood vessels
Temperature
Stress responses
Autonomic nervous-system activity
This may help explain why some women become more aware of their heartbeat during the menopause transition.
However, the presence of palpitations alone cannot prove that hormones are responsible.
Palpitations and Hot Flashes Can Occur Together
This is one of the strongest clues that palpitations may be occurring as part of the menopause transition.
A typical hot flash can involve:
Sudden heat → flushing → sweating → sometimes anxiety or chills → rapid heartbeat
The Menopause Society notes that some women experience a rapid heartbeat during hot flashes, which typically last about one to five minutes. The Menopause Society
So if your heart racing repeatedly occurs at the same time as:
Sudden warmth
Facial or chest flushing
Sweating
Night sweats
the episodes may be related to vasomotor symptoms.
But even then, persistent or concerning palpitations shouldn't simply be assumed to be hormonal.
What Else Can Cause Heart Palpitations?
This is where medical evaluation becomes important.
Palpitations have many possible causes.
Caffeine
Coffee, tea, energy drinks, and other stimulants may trigger palpitations in some people.
Alcohol
Alcohol can also provoke palpitations and, in some circumstances, abnormal heart rhythms.
Stress and Anxiety
Stress, anxiety, panic attacks, and emotional stimulation can make the heartbeat faster or more noticeable.
Lack of Sleep
Poor sleep is a recognized trigger for palpitations—and sleep disruption is itself common during perimenopause. nhs.uk
Dehydration
Fluid and electrolyte disturbances may contribute to palpitations. Cleveland Clinic
Medications
Certain medications, including some decongestants and other stimulants, may trigger palpitations.
Don't stop a prescribed medication on your own. Discuss possible side effects with your healthcare provider.
Could It Be Your Thyroid?
Yes.
An overactive thyroid can cause:
Fast heartbeat
Palpitations
Tremor
Anxiety
Heat intolerance
Sweating
Weight loss
Sleep problems
Notice the problem?
Several of these symptoms can resemble perimenopause.
That's why simply assuming:
“I'm 47, so it must be hormones”
can be misleading.
Depending on your symptoms and medical history, thyroid testing may be appropriate.
Could Iron Deficiency or Anemia Cause Palpitations?
Yes.
This is particularly relevant during perimenopause because menstrual bleeding can sometimes become heavier or more irregular.
Significant blood loss may contribute to iron deficiency or anemia.
Possible symptoms include:
Fatigue
Weakness
Shortness of breath
Dizziness
Reduced exercise tolerance
Palpitations
Anemia is among the recognized medical causes of palpitations. Cleveland Clinic
Depending on the clinical situation, a physician may consider:
CBC + ferritin ± additional iron studies
This is another reason palpitations during perimenopause shouldn't automatically be attributed to estrogen.
Could It Actually Be an Arrhythmia?
Sometimes.
An arrhythmia is an abnormal heart rhythm.
Examples include:
Atrial fibrillation
Supraventricular tachycardia (SVT)
Atrial flutter
Other rhythm disturbances
Atrial fibrillation, for example, may cause a racing, irregular, or flip-flopping heartbeat, as well as fatigue, shortness of breath, dizziness, or chest discomfort. Heart and Stroke
This doesn't mean every flutter is atrial fibrillation.
Far from it.
But it does mean that age and menopause status should never be used to dismiss cardiac symptoms without appropriate consideration.
When Do Palpitations Seem More Likely to Be Menopause-Related?
There is no symptom pattern that can definitively prove palpitations are hormonal.
However, menopause may be more plausible when palpitations:
Begin around the same time as other perimenopause symptoms
Occur alongside hot flashes or night sweats
Appear during a period of menstrual-cycle changes
Are brief and intermittent
Occur without concerning accompanying symptoms
Have been medically evaluated when appropriate and no cardiac or other medical cause has been identified
Even in that situation, the correct conclusion isn't necessarily:
“Definitely estrogen.”
It may simply mean that the menopause transition is a reasonable contributor.
When Should Heart Palpitations Be Evaluated?
Talk with a healthcare professional if your palpitations:
Keep returning
Are becoming more frequent
Last longer than usual
Feel significantly different from your normal heartbeat
Are associated with a very fast or irregular heartbeat
Occur with exertion
Are new and unexplained
Occur if you already have heart disease or significant cardiovascular risk factors
The NHS specifically recommends seeking medical advice for recurrent or worsening palpitations. nhs.uk
When Are Palpitations an Emergency?
This distinction is especially important for a medical article.
Seek urgent/emergency medical care if palpitations occur with symptoms such as:
Chest pain or significant chest discomfort
Severe shortness of breath
Fainting or loss of consciousness
Severe dizziness or feeling as though you may faint
These combinations may indicate a more serious cardiovascular problem.
Heart & Stroke Canada advises calling 9-1-1 for chest discomfort or other signs of a heart attack. Heart and Stroke
Don't assume these symptoms are “just menopause.”
How Are Heart Palpitations Evaluated?
Evaluation starts with the story.
Your physician may ask:
When did they begin?
How frequently do they occur?
How long do they last?
Does the heartbeat feel fast, irregular, or simply strong?
Do they occur with hot flashes?
Are they triggered by exercise?
Are you dizzy or short of breath?
How much caffeine or alcohol do you consume?
What medications and supplements are you taking?
Have your menstrual periods become heavier?
Do you have a history of thyroid or heart disease?
Depending on the situation, evaluation may include a physical examination, pulse and blood pressure assessment, and an electrocardiogram (ECG).
What If the ECG Is Normal?
An ECG records your heart rhythm during a short period.
But palpitations may not happen while you're sitting in the doctor's office.
If symptoms are intermittent, your physician may recommend longer rhythm monitoring, such as a Holter monitor or another ambulatory cardiac monitor, to record your heartbeat during normal daily life. Cleveland Clinic
Additional testing depends on the history and findings.
What Blood Tests Might Be Considered?
There isn't one universal “palpitations panel.”
Depending on symptoms and medical history, your clinician may consider testing related to:
Anemia or iron deficiency
Thyroid function
Electrolytes
Glucose
Other conditions suggested by your history
Testing should be targeted rather than simply ordering every available hormone test.
Do You Need an Estrogen Test?
Usually, a single estrogen level isn't very helpful for determining whether palpitations are caused by perimenopause.
Hormone levels can fluctuate substantially during the menopause transition.
In women of typical perimenopausal age, the overall clinical picture—including menstrual changes and other menopause symptoms—is often more informative than one isolated estradiol measurement.
A normal or abnormal estrogen result also wouldn't exclude other cardiac or medical causes of palpitations.
Can Hormone Therapy Help Palpitations?
This requires nuance.
Menopausal hormone therapy is an established treatment for bothersome vasomotor symptoms, particularly hot flashes and night sweats.
If palpitations consistently occur as part of hot-flash episodes, treating the overall menopause symptom pattern may potentially help some women.
But hormone therapy should not be prescribed simply as treatment for unexplained palpitations before other important causes have been considered.
And menopausal hormone therapy is not a treatment for an arrhythmia.
The decision to use hormone therapy should be based on the woman's overall menopause symptoms, medical history, risks, goals, and treatment preferences.
What Can You Track at Home?
Keeping a brief symptom diary can make your medical visit much more useful.
Record:
Time: When did it happen?
Duration: Seconds or minutes?
Heart sensation: Racing, fluttering, pounding, skipped beats?
Hot flash: Yes or no?
Menstrual cycle: Where are you in your cycle?
Caffeine/alcohol: What did you consume beforehand?
Exercise: Did it happen during exertion?
Sleep: Did you sleep poorly the previous night?
Associated symptoms: Chest discomfort, shortness of breath, dizziness, fainting?
Patterns can help your clinician determine what needs further investigation.
Don't Ignore Cardiovascular Health During Menopause
There is a broader reason to take heart symptoms seriously.
Cardiovascular disease risk becomes increasingly important as women age.
Menopause care therefore provides an opportunity to review cardiovascular health more broadly, including factors such as:
Blood pressure
Cholesterol
Glucose
Smoking
Physical activity
Sleep
Family history
Body composition
Other cardiovascular risk factors
This doesn't mean menopause itself explains every heart symptom.
It means midlife is an important time to pay attention to cardiovascular health rather than dismiss it.
The CONDUCT™ Method
At ConductMD, palpitations during perimenopause are not viewed through hormones alone.
The CONDUCT™ Method helps us consider several interconnected systems.
Could stress, anxiety, poor sleep, or autonomic activation be making the heartbeat more noticeable?
Did palpitations begin alongside menstrual changes, hot flashes, night sweats, or other perimenopause symptoms?
Could hydration, dietary patterns, glucose regulation, caffeine, alcohol, or nutritional issues be relevant?
Are medications, supplements, gastrointestinal issues, or nutrient absorption concerns part of the broader health picture?
Are nighttime urinary symptoms or other menopause-related concerns disrupting sleep and contributing to overall symptom burden?
What does the woman's broader cardiovascular and metabolic risk profile look like?
Could thyroid disease, anemia, iron deficiency, or another medical condition be contributing?
The purpose isn't to blame every system.
It's to avoid prematurely deciding:
“It's just hormones.”

Frequently Asked Questions
Are heart palpitations normal during perimenopause?
Palpitations can occur during perimenopause and menopause, and some women experience a rapid heartbeat during hot flashes. However, new or recurrent palpitations shouldn't automatically be assumed to be hormonal. The Menopause Society
Can low estrogen cause heart palpitations?
Hormonal changes during the menopause transition may contribute to palpitations, but an individual episode cannot reliably be attributed to low estrogen alone. Other potential causes should be considered.
Why do I get heart palpitations at night during perimenopause?
Possible contributors include night sweats, stress, poor sleep, caffeine or alcohol, medications, hormonal changes, thyroid disease, anemia, or an arrhythmia. Nighttime timing alone doesn't establish the cause. Cleveland Clinic
Can anxiety cause palpitations?
Yes. Stress and anxiety are common triggers for palpitations. However, unexplained cardiac symptoms shouldn't automatically be labeled anxiety without appropriate assessment. nhs.uk
Can thyroid problems cause palpitations?
Yes. Hyperthyroidism can cause a fast heartbeat and palpitations, which is why thyroid function may be considered during evaluation when clinically appropriate.
Should I see a cardiologist for palpitations during menopause?
Not every palpitation requires specialist care. Your primary-care or menopause clinician can often begin the evaluation and determine whether ECG testing, ambulatory monitoring, cardiology assessment, or other investigation is appropriate.
Can HRT stop heart palpitations?
Hormone therapy may improve vasomotor symptoms in appropriate candidates, and some women may notice improvement if their palpitations accompany hot flashes. But HRT should not be used as a substitute for evaluating unexplained palpitations or treating a cardiac arrhythmia.
The Bottom Line
Heart palpitations can be part of perimenopause.
But “can be hormonal” and “must be hormonal” are very different statements.
Palpitations may also be related to:
Stress • Sleep • Caffeine • Alcohol • Medications • Dehydration • Anemia • Thyroid disease • Heart rhythm disorders
If palpitations begin alongside hot flashes, night sweats, and menstrual changes, the menopause transition may be contributing.
But heart symptoms deserve appropriate attention—particularly when they're new, recurrent, prolonged, associated with exertion, or accompanied by chest discomfort, shortness of breath, severe dizziness, or fainting.
At ConductMD, we don't automatically ask:
“Which hormone is causing this?”
We ask:
“What could be causing this symptom, what needs to be ruled out, and how does it fit into the woman's overall health?”
