Palpitations and heart attack worry
Start here in 30 seconds

A flutter. A thump. A heart that races without reason. When this happens in your 40s or 50s, the mind goes straight to the worst explanation — and it goes there fast.

This page cannot tell you what is causing your palpitations. It can help you check the real red flags right now, understand what commonly drives these sensations in midlife, and take a clear pattern to a clinician.

Safety first. Pattern next. Clarity in ten minutes.

Common reasons

Palpitations can be triggered by stress, poor sleep, caffeine, dehydration, alcohol, illness, skipped meals, anxiety, and hormonal transition. In midlife, the nervous system can become more reactive — making the heart's rhythm feel more noticeable even when it is beating normally.

The aim is not to self-diagnose. It is to check safety, identify the pattern, and bring clarity to a clinician.

When to get urgent help

Most palpitations are not dangerous. This section is here so you do not have to guess.

Call 999 now if you have
Chest pain or pressure
Fainting, collapse, or feeling like you might lose consciousness
Severe breathlessness at rest
Sudden weakness on one side, slurred speech, or sudden confusion
Symptoms that feel sudden, severe, and rapidly worsening

If none of the above apply, it is reasonable to track the pattern for 7 days and speak to a clinician.

When it may be hormonal

Hormonal transition can increase nervous system reactivity and sleep sensitivity. Some women notice palpitations:

Only a clinician can assess and rule out cardiac and other medical causes. This section is about recognised patterns — not reassurance that it is safe to ignore.

  • Alongside anxiety, inner shakiness, or a "wired" feeling
  • After broken sleep, night sweats, or high-stress weeks
  • In episodes that last seconds to minutes and then fully resolve
What to track for 7 days
  • When it happened (time of day, what you were doing)
  • What it felt like (flutter / thump / racing / skipped beat)
  • How long it lasted
  • What happened just before (caffeine, stress, rushing, alcohol, dehydration, skipped meal, poor sleep)
  • Any paired symptoms (dizziness, breathlessness, chest tightness, night sweats, panic feeling)
  • Sleep quality the night before

These are general wellbeing steps — not a substitute for medical assessment.

Awake
Awake
  1. A slower exhale for 60 to 90 seconds (in for 4, out for 6) because a longer exhale directly activates the parasympathetic nervous system, measurably reducing heart rate and sympathetic drive within minutes
  2. Water first, then caffeine later if you can because dehydration is one of the most common and most immediately correctable palpitation triggers — and caffeine on a dehydrated system amplifies the effect
Nourish
Nourish
  1. Eat something steady if you have gone more than 4 hours without food because long gaps between meals trigger an adrenaline release from low blood glucose — and adrenaline makes the heart rhythm feel louder
  2. Reduce stimulants today if palpitations are active because caffeine and energy drinks lower the threshold for episodes in women whose nervous system is already more reactive during hormonal transition
Drift
Drift
  1. Keep the evening lower in stimulation because late stress activation and charged conversations increase the likelihood of night-time episodes and make it harder to assess whether the pattern is improving
  2. Avoid alcohol on days when palpitations have been present because alcohol is a consistent palpitation amplifier — particularly for night-time episodes — and a clear test week gives you useful data
Clinician-ready script

"I have been noticing palpitations since [timeframe]. They tend to happen with [poor sleep / stress / caffeine / alcohol / night sweats]. Could we rule out cardiac and other causes, and discuss whether hormonal transition could be contributing?"

Next best action
  • If symptoms are new, worrying, or repeating, track for 7 days and bring the pattern to a clinician
  • Use GP Notes in the SHEIQ app to generate a clear summary for your appointment
  • Read the matching symptom guide for palpitations for day-to-day support

FAQs

Can hormones cause palpitations?

Yes. Palpitations are commonly reported during hormonal transition — often alongside anxiety, sleep disruption, and inner shakiness.


How do I know if it is anxiety or my heart?

Anxiety can amplify sensations, but new or persistent palpitations always deserve clinician assessment. The urgent help section above is the place to start. Track the pattern and bring it.


Should I stop caffeine immediately?

Not necessarily. Reduce it for a few days, track whether the pattern changes, and assess honestly. Abrupt withdrawal can cause its own symptoms.


What tests might a clinician consider?

Depending on your history and symptom pattern, a clinician may consider an ECG, pulse assessment, blood tests, and medication review.
