Palpitations
Definition
Heart palpitations are the sensation of a fast-beating, fluttering, or pounding heart. During perimenopause, these episodes are common and are typically related to the autonomic nervous system's response to fluctuating estrogen rather than a primary heart defect.
In Depth
Palpitations are a recognized vasomotor symptom of the menopause transition. Estrogen helps regulate the autonomic nervous system, which controls "automatic" functions like heart rate and body temperature. When estrogen levels spike or crash—as they do frequently in perimenopause—the nervous system can become over-activated, leading to sudden bursts of rapid or irregular heartbeats. These are often experienced during or just before a hot flash. While these sensations can be alarming, they are usually benign in healthy women. However, because cardiovascular risk profiles change after menopause, persistent or new palpitations should always be screened to rule out underlying arrhythmias or changes in arterial health.
Why It Matters
Palpitations are a frequent source of health anxiety for women in perimenopause. Recognizing them as a symptom of a sensitized nervous system helps provide clarity and focus on overall cardiovascular health management.
