What are heart palpitations?
Most of the time you won’t notice your heartbeat, but if you suddenly become aware of it, this may concern you or come as a surprise. The feeling of your heart beating irregularly or rapidly is described as a palpitation.
Palpitations can range from simply being aware of your heart’s activity to the sensation of it beating faster and harder than usual. It can sometimes feel like your heart is missing beats.
Although changes to your heartbeat are not always serious, they can be worrying.

- alcohol alcohol and nicotine nicotine
- taking certain medicines (such as ephedrine and theophylline)
- taking recreational drugs (such as cocaine and amphetamines).
If you have heart palpitations, or irregular or rapid heartbeats, there are a number of things you can do:
- try to sit down and relax or find somewhere quiet to rest
- keep yourself calm and in a comfortable position
- try not to panic as this can make your symptoms worse
- you may find it helpful to loosen any restrictive (tight) clothing that can affect your breathing, such as your collar button and tie
- avoid any stimulants that could make your palpitations worse – this includes caffeine, nicotine, alcohol and recreational drugs.
