Heart palpitations are when your heartbeat becomes more noticeable. They're usually harmless, but get help if you keep getting them or you also have other symptoms.

When you have heart palpitations, your heartbeat feels uncomfortable or unusual. You may feel it in your chest, neck or throat.

Your heartbeat may feel like it is:

• racing or beating very fast
• irregular, with skipped or extra beats (ectopic beats)
• pounding or thumping
• fluttering

Heart palpitations can last seconds, minutes or longer.

Heart palpitations are common and not usually a sign of anything serious.

Common causes include:

• strenuous exercise
• lack of sleep
• stress and anxiety
• medicines (check the leaflet that comes with the medicine)
• alcohol, caffeine, nicotine and recreational drugs

Sometimes heart palpitations can be a sign you're going through the menopause. Some people get them during pregnancy.

Less often, they can be caused by a condition such as iron deficiency anaemia, an overactive thyroid (hyperthyroidism) or a heart rhythm problem (arrhythmia).

Treatment for heart palpitations depends on the cause. They often do not need to be treated.

Avoiding things that can trigger palpitations, such as stress, smoking, caffeine and alcohol, can help.

You may have an electrocardiogram (ECG) to help find out what the cause might be. This is a test where small pads are stuck to your skin to check the electrical signals coming from your heart.

If your palpitations are caused by a heart problem, you may need medicines or a procedure to help correct your heartbeat.
