Lifestyle triggers can include:
Feeling nervous, anxious or excited
If this is the cause of your palpitations, it's sensible to try to reduce your stress levels.

If you experience palpitations regularly and you also have feelings of anxiety, stress and panic, you may be experiencing panic attacks.
Panic attacks can be very frightening and intense, but they are not dangerous. However, it may help if you discuss these with a health professional.

Less commonly, palpitations can be a side effect of some types of medicine, such as asthma inhalers or tablets for a thyroid problem.
This may be particularly noticeable if you have just started taking the medication.
Speak to your GP if you think medication may be responsible for your palpitations. Don't stop taking a treatment without consulting your GP first.
Periods, pregnancy and the menopause
Sometimes the hormone changes that happen during a woman’s period, during pregnancy or around the menopause can cause palpitations.
These may only be temporary, and are often nothing to worry about.
The following conditions can make the heart beat faster, stronger or more irregularly, so can be a cause of heart palpitations:
- an overactive thyroid
- low blood sugar level
- anaemia (low red blood count)
- some types of low blood pressure
- dehydration (not enough fluid in the body)
- a heart problem
Heart specific problems
All palpitations should be discussed with your GP. They might want to do a few tests and ask you some questions to rule out heart problems, especially if you have had a heart problem in the past.
Some heart specific problems are covered below.
It could be found that you have a heart rhythm problem, also known as arrhythmia.
Your GP will be able to arrange for you to have an electrocardiogram (ECG) to assess your heart rate and rhythm. This may confirm whether there is a problem, and whether treatment is needed.
However, often the ECG is entirely normal especially if you aren't having palpitations at the time. Further tests may then be needed, which can be done by your GP or by your local hospital.
Atrial fibrillation is the most common heart rhythm problem, affecting approximately 1,000,000 people in the UK.
It can cause episodes of a fast, irregular heart rate, which can feel like a persistent heart flutter, and you may feel dizzy, short of breath and extremely tired.
Atrial fibrillation is generally not life threatening, but can be uncomfortable and often needs treating.
Atrial fibrillation often requires medical assessment. Some people may need treatment to control the condition, particularly if they are at higher risk of developing a stroke.

Supraventricular tachycardia (SVT)
A similar heart rhythm problem, called supraventricular tachycardia (SVT), also causes episodes of an abnormally fast heart rate, but the heart rate is normally steady and not irregular.
Attacks of SVT are usually harmless and tend to settle on their own without treatment. However, if they are prolonged or you feel unwell or experience symptoms such as dizziness or shortness of breath, you should seek help from a doctor.
