Your heart suddenly races for no reason. It flutters. It pounds. It skips a beat. You are lying in bed at 2am wondering if you are having a heart attack. Perimenopause heart palpitations are one of the most frightening — and least talked about — symptoms of the transition. Yet up to 40% of perimenopausal women experience them.
Why Does Perimenopause Cause Palpitations?
Oestrogen has a direct effect on the cardiovascular system. It helps regulate heart rate, blood pressure, and the electrical conduction system of the heart. When oestrogen levels fluctuate erratically during perimenopause, the heart's electrical system can become temporarily dysregulated — causing palpitations, racing episodes, or the sensation of skipped beats.
Palpitations are also closely linked to hot flushes (the same vasomotor response that causes flushing also affects heart rate), anxiety (which surges during perimenopause), and sleep deprivation (which stresses the cardiovascular system).
What Do Perimenopause Palpitations Feel Like?
- A sudden racing or pounding heartbeat
- A fluttering sensation in the chest
- The feeling that your heart has 'skipped' a beat
- A brief irregular rhythm that then returns to normal
- Palpitations that wake you from sleep
- Episodes that last seconds to a few minutes
⚠️ 🚨 Seek immediate medical attention if: your palpitations are accompanied by chest pain, shortness of breath, dizziness, or fainting; episodes last longer than 15 minutes; or you have a history of heart disease.
When Are They Harmless vs. When to Worry?
Most perimenopause palpitations are benign — they are uncomfortable and frightening but not dangerous. However, because heart disease risk does increase after menopause, it is always worth getting palpitations assessed by your GP, especially if they are new, frequent, or accompanied by other symptoms.
Your GP may recommend an ECG (electrocardiogram), a 24-hour Holter monitor, thyroid function tests, and blood pressure monitoring. These tests can rule out cardiac arrhythmias and other causes.
Managing Perimenopause Palpitations
- 1Identify and avoid triggers — caffeine, alcohol, stress, and dehydration commonly worsen palpitations
- 2MHT — many women find hormone therapy significantly reduces palpitation frequency
- 3Magnesium glycinate — supports healthy heart rhythm and is often depleted during perimenopause
- 4Stress management — since anxiety and palpitations are closely linked, addressing anxiety helps both
- 5Regular aerobic exercise — improves cardiovascular regulation over time
- 6Adequate sleep — sleep deprivation significantly worsens palpitations
