Why Your Heart Races for No Obvious Reason
A heart that flutters, races, or seems to skip a beat — sometimes at rest, sometimes in the middle of a hot flash, sometimes for no reason you can identify — can be one of the more unsettling symptoms of perimenopause. According to Cleveland Clinic, up to 42% of perimenopausal women report heart palpitations, and AARP reporting suggests the figure is even higher in postmenopausal women, with heart rate sometimes rising 8 to 16 beats per minute during a hot flash.
The mechanism comes back to estrogen's role in the autonomic nervous system — the part of your nervous system that quietly regulates things like heart rate, blood pressure, and temperature. When estrogen levels fluctuate, that regulation becomes less stable, and the heart can register the chaos as occasional irregular beats.
Zubina Mawji, MD, MPH, a menopause specialist at Cleveland Clinic Canada, has reassured patients that this kind of palpitation "doesn't typically cause a dangerous heart rhythm, but it can be very unsettling." That reassurance, though, comes with an important caveat: palpitations should not be self-diagnosed.
A baseline cardiology evaluation is a reasonable step, particularly because Mayo Clinic notes that the decline in estrogen during perimenopause is also associated with an increased risk of cardiovascular disease — making this exactly the moment to establish a baseline rather than assume everything is hormonal. Once cardiac causes have been ruled out, a menopause-trained clinician can help address the hormonal piece.
Heart palpitations accompanied by chest pain, shortness of breath, dizziness, or fainting are not something to wait on. These deserve same-day evaluation regardless of whether perimenopause is also part of the picture.
