Palpitations in menopause: when they are harmless, when they are not

What you feel has a name, and it is studied

The heart taking off at a gallop in the middle of the night. A missed beat, then a stronger one. An acceleration at the end of a hot flash, when the whole body is coming back down. Many women describe these sensations in their fifties, and many do not mention them in consultation, because they do not connect them to menopause, or because they are afraid of being taken for anxious.

Research took an interest in them later than in hot flashes, and a review of the very way of measuring menopausal palpitations was published to lay the groundwork for the subject³. A scoping review then gathered what we know about the factors associated with them².

In other words : what you feel is described, documented, and is in no way a whim.

What the SWAN study observed

SWAN is one of the large cohorts that follow women throughout the menopause transition. One analysis focused specifically on palpitations : their course over time, the characteristics of the women concerned, and their links with markers of subclinical cardiovascular disease¹.

This last point deserves a careful reading. That a symptom is associated with vascular markers does not mean it causes them, nor that it announces an event. It means the complaint deserves to be listened to rather than brushed aside, and that it can be an opportunity to look at overall cardiovascular health: blood pressure, lipids, smoking, physical activity.

This is in fact the right moment to do so : women's cardiovascular risk changes after menopause, as we explain in our article on women's cardiovascular health.

Why the heart races at this time of life

Several mechanisms overlap, and they do not exclude one another.

Vasomotor activity. A hot flash is a reaction of the entire thermal regulation system : vasodilation, sweating, acceleration of the rhythm. The palpitations that accompany or follow a hot flash are the cardiac part of that same phenomenon. Work has examined the link between hot flashes, anxiety and midlife palpitations⁴.

Sleep. Nighttime awakenings, sleep apnea which becomes more frequent after menopause, the 3 a.m. hyperarousal : the heart takes part in all of it. See our article on sleep apnea at menopause.

Anxiety. It amplifies perception as much as it speeds up the rhythm. It is not "in your head" : it is a real physiological loop, in which the attention paid to the heart makes every beat more audible.

The other causes, not to be forgotten. An overactive thyroid, anemia, an iron deficiency, too much caffeine or alcohol, certain medications. Hyperthyroidism can mimic a good part of the menopausal picture, palpitations included.

The signs that require seeing a doctor without delay

Here is the part to remember even if you read nothing else. Seek emergency care (emergency services, not an appointment in three weeks) if the palpitations come with :

• fainting or loss of consciousness ;
• pain in the chest, jaw, arm or back ;
• unusual breathlessness, at rest or on minimal exertion ;
• if they occur on exertion rather than at rest ;
• if they last a long time, stay very fast, or if the pulse is clearly irregular ;
• if there is a family history of sudden death or of a rhythm disorder ;
• if signs appear that the HAS describes as signs of poor tolerance : swelling of the legs or recent breathlessness suggesting heart failure, recent or worsening chest pain, blood pressure dropping with a feeling of weakness.

In these situations, call 15, or 112 from a mobile phone, rather than getting behind the wheel. These are the cases where management is decided in hours, not in weeks.

Outside these situations, a scheduled consultation is still warranted if the symptom is new, if it recurs, or if it stops you sleeping.

What the doctor will look for

The approach is well codified, and a review intended for primary care doctors describes its steps⁵ : precise history-taking, examination, electrocardiogram, blood work (thyroid, hemoglobin, ferritin, electrolytes).

The in-office electrocardiogram captures only the present moment. If the symptom is intermittent, a prolonged recording (a 24 or 48 hour Holter, or longer) makes it possible to see what happens at the moment you feel it. That is why you will often be asked to note the time of each episode.

Two points, absent from many articles for the general public, are worth knowing because the professional societies insist on them. First, the European cardiology guidelines consider that an electrocardiogram recorded during the episode is the ideal situation, and they explicitly encourage patients to try to have their tracing recorded at the moment the symptom occurs. In practice : if your heart races for a long time, it is not absurd to see a doctor during the episode rather than after. Second, these same guidelines consider that a resting 12-lead electrocardiogram and an echocardiogram are part of the initial work-up. So if you are offered an ultrasound of the heart, it is not excessive zeal.

In France, the HAS care pathway guide on atrial fibrillation recalls that the diagnosis of a rhythm disorder rests on a 12-lead electrocardiogram, and that palpitations are among the symptoms that should lead to one.

Work conducted in older women screened for atrial fibrillation found frequent premature beats and runs of nonsustained ventricular tachycardia⁷. This result is a reminder of two things : abnormalities can exist without being felt, and most of those found are benign.

What helps, when the work-up is reassuring

When the heart has been examined and declared healthy, the goal changes : it is no longer about ruling out a danger but about living more calmly with an unpleasant symptom.

A review looked at the effect of treatments for menopausal symptoms on palpitations⁶. It is a logical lead when palpitations accompany hot flashes : treating the vasomotor symptoms can act on both. This decision is made case by case: our article on hormone therapy sets out the framework.

In parallel, three simple levers : cutting caffeine and alcohol in the evening, treating sleep rather than putting up with it, and working on slow breathing, whose effect on heart rate is immediate and measurable.

In short

Midlife palpitations are frequent, documented, and most often benign. They are not, for all that, to be ignored : they deserve an electrocardiogram, blood work, and sometimes a prolonged recording.

The right mindset is neither panic nor denial. It is : "I note it down, I see a doctor, I get it checked, and if all is well, I deal with what keeps it going."
