Heart Palpitations During Perimenopause: Causes and When to Worry
Heart palpitations can be alarming during perimenopause. Research explains why they happen, when they're normal, and when to seek medical attention.
A racing heart. A fluttering sensation in your chest. Skipped beats that take your breath away. If you have experienced heart palpitations during perimenopause, you may have wondered whether something is seriously wrong.
The good news: research shows that palpitations are common during perimenopause and usually benign. Understanding why they happen can help ease your concerns while knowing when to seek medical attention.
How Common Are Perimenopausal Palpitations?
Research suggests that heart palpitations affect approximately 25-40% of perimenopausal women. A study published in the journal Menopause (2014) surveyed over 1,000 women and found that palpitations were among the top reported symptoms during the menopausal transition.
The Study of Women's Health Across the Nation (SWAN) has documented increased cardiovascular symptoms during perimenopause, with palpitations often occurring alongside hot flashes and night sweats.
Why Does Perimenopause Cause Palpitations?
The Estrogen-Heart Connection
Research has established multiple pathways through which fluctuating estrogen affects heart rhythm.
Autonomic Nervous System Effects A study in the American Journal of Physiology (2011) found that estrogen influences the autonomic nervous system, which controls heart rate. During perimenopause, erratic estrogen levels can cause dysregulation, leading to episodes of rapid heartbeat or irregular rhythms.
Direct Cardiac Effects Research from the Journal of the American College of Cardiology (2006) showed that estrogen receptors exist in heart tissue. Fluctuating hormone levels may directly affect electrical signaling in the heart.
Blood Vessel Changes Studies dating back to the 1990s established that estrogen helps maintain blood vessel flexibility. As levels fluctuate, blood pressure can become more variable, which can trigger palpitations.
The Hot Flash Connection
Research consistently links palpitations to vasomotor symptoms. A 2016 study in Menopause found that women who experienced severe hot flashes were significantly more likely to report palpitations.
The mechanism: hot flashes involve a surge of adrenaline, which directly increases heart rate. If you notice palpitations occurring with hot flashes or night sweats, this connection is likely the cause.
Sleep Deprivation
Sleep problems during perimenopause can contribute to palpitations. Research from the Journal of Clinical Sleep Medicine found that sleep deprivation increases sympathetic nervous system activity, which can trigger irregular heartbeats.
Anxiety and Stress
The relationship between anxiety and palpitations is bidirectional. Anxiety causes palpitations, and palpitations cause anxiety. Research shows that perimenopausal women have elevated cortisol and adrenaline responses to stress, which can manifest as heart symptoms.
Types of Palpitations
Women describe perimenopausal palpitations in several ways:
Racing heart (tachycardia)
- Heart rate suddenly increases
- Often occurs with hot flashes
- Usually settles within minutes
Fluttering or quivering
- Sensation of rapid, light beats
- May feel like the heart is "vibrating"
Skipped beats (ectopic beats)
- Feeling that the heart paused or skipped
- Often followed by a stronger beat
- Very common and usually harmless
Pounding heart
- Awareness of forceful heartbeats
- Can occur at rest or with activity
When Palpitations Are Typically Benign
Research suggests palpitations during perimenopause are usually harmless when they:
- Last only seconds to a few minutes
- Occur with hot flashes or night sweats
- Happen during times of stress or anxiety
- Are not accompanied by other symptoms
- Resolve on their own
- Do not significantly limit activity
A study in the journal Circulation (2013) found that isolated palpitations without other cardiac symptoms rarely indicate serious heart problems in otherwise healthy women.
Warning Signs That Need Attention
While most perimenopausal palpitations are benign, certain symptoms warrant prompt medical evaluation:
Seek immediate care if palpitations are accompanied by:
- Chest pain or pressure
- Difficulty breathing
- Dizziness or fainting
- Severe shortness of breath
Schedule a medical appointment if you experience:
- Palpitations lasting longer than a few minutes
- Episodes that seem to be worsening
- Palpitations during exercise
- Family history of heart problems or sudden cardiac death
- History of heart disease or heart murmur
- Palpitations affecting your daily activities
Medical Evaluation
If your healthcare provider wants to investigate your palpitations, common tests include:
Electrocardiogram (ECG) Records the heart's electrical activity at a single point in time. Often normal if palpitations are not occurring during the test.
Holter Monitor A portable ECG worn for 24-48 hours that captures heart rhythm during normal activities.
Event Monitor Worn for longer periods (up to 30 days), activated when you feel palpitations.
Blood Tests May check thyroid function, electrolytes, and anemia, all of which can cause palpitations.
Echocardiogram Ultrasound of the heart to check structure and function if indicated.
Evidence-Based Management Strategies
Address Triggers
Research supports identifying and managing triggers:
Caffeine Studies show caffeine can trigger palpitations in sensitive individuals. Try reducing or eliminating coffee, tea, and energy drinks to see if symptoms improve.
Alcohol Research in the Journal of the American College of Cardiology (2016) linked alcohol consumption to increased risk of atrial fibrillation. Even moderate drinking can trigger palpitations in some women.
Dehydration Can affect heart rhythm. Ensure adequate fluid intake throughout the day.
Manage Hot Flashes
Since palpitations often accompany hot flashes, strategies that reduce vasomotor symptoms may help. Hormone therapy effectively reduces hot flashes in most women and may decrease associated palpitations.
Stress and Anxiety Reduction
Given the strong mind-heart connection, stress management can reduce palpitations:
Deep breathing Research shows slow, diaphragmatic breathing activates the parasympathetic nervous system and can slow heart rate within minutes.
Mindfulness A study in the Journal of the American Heart Association (2019) found that mindfulness training reduced palpitation frequency in participants with benign arrhythmias.
Regular exercise Counterintuitively, regular aerobic exercise helps regulate heart rhythm. Research from the British Journal of Sports Medicine shows that physically fit women have more stable autonomic nervous system function.
Optimize Sleep
Addressing sleep problems can reduce palpitations. Prioritize sleep hygiene and discuss treatment options with your provider if night sweats are disrupting rest.
Consider Supplements Carefully
Some supplements may affect heart rhythm:
Magnesium Research supports magnesium for some types of palpitations. A study in Annals of Noninvasive Electrocardiology found magnesium supplementation reduced palpitation frequency.
Avoid stimulating supplements Some herbal supplements can worsen palpitations. Always discuss supplements with your healthcare provider.

Hormone Therapy and Heart Health
The relationship between hormone therapy and cardiovascular health has been extensively studied.
Current research suggests that for healthy women beginning hormone therapy within 10 years of menopause or before age 60:
- HRT is not associated with increased cardiovascular risk
- May actually have cardioprotective effects
- Can reduce palpitations by stabilizing hormone levels and reducing hot flashes
Discuss the benefits and risks with your healthcare provider based on your individual health profile.
The Reassuring Reality
Research consistently shows that while palpitations during perimenopause are unsettling, they are rarely dangerous in otherwise healthy women. A 2017 review in the European Heart Journal found that benign palpitations are extremely common in the general population and do not increase cardiovascular risk.
The challenge is distinguishing benign palpitations from those requiring treatment. Working with your healthcare provider to rule out underlying conditions can provide peace of mind.
Moving Forward
Heart palpitations during perimenopause are a normal, if unpleasant, part of the hormonal transition. Understanding that fluctuating estrogen affects your cardiovascular system can help you respond calmly when symptoms occur.
Track your palpitations, noting when they occur and any associated triggers or symptoms. This information helps your healthcare provider assess whether further evaluation is needed and identify patterns that might point to specific triggers.
Most importantly, do not hesitate to seek medical attention if you are concerned. While palpitations are usually benign, your peace of mind matters, and ruling out other causes is worthwhile.
