Heart palpitations and ectopic beats

Read out about the main causes of heart palpitations and ectopic beats and find out when to get medical advice.

11 October 2018


Heart palpitations are heartbeats that suddenly become more noticeable.

Your heart may feel like it's pounding, fluttering or beating irregularly, often for just a few seconds or minutes. You may also feel these sensations in your throat or neck.

Palpitations may seem alarming, but in most cases they're harmless and aren't a sign of a serious problem.

Sometimes you may feel an extra or missed beat. These are known as ectopic beats and are also usually nothing to worry about.

Causes of heart palpitations include:

  • lifestyle triggers
  • emotions and psychological triggers

Lifestyle triggers

Common triggers of heart palpitations include:

In these cases, the palpitations should go away on their own. Avoiding these triggers may help stop them coming back.

Speak to your GP if you think medication may be causing your palpitations. But don't stop taking a prescribed treatment without first getting medical advice.

Hormone changes

Heart palpitations in women can sometimes be the result of hormonal changes that occur during:

  • periods ↗
  • pregnancy
  • the menopause ↗ – when a woman stops having periods and is no longer able to get pregnant naturally

In these cases, the palpitations are usually temporary and not a cause for concern.

Heart rhythm problems

Palpitations are sometimes caused by a problem with the heart rhythm, such as:

  • atrial fibrillation ↗ – a heart rhythm problem that can cause a fast, irregular heart rate
  • atrial flutter – a rhythm disturbance that can be fast and either regular or irregular
  • supraventricular tachycardia (SVT) ↗ – a heart rhythm problem that causes episodes of an abnormally fast but regular heart rate; it's common in young, otherwise healthy, people
  • ventricular tachycardia – a more serious and typically fast, regular heart rhythm disturbance that can be associated with dizziness or blackouts

These conditions are known as arrhythmias ↗.

Heart conditions

Some palpitations may be associated with other problems with the heart, such as:

Some of these conditions can be serious and often require treatment.

Other medical conditions

The following conditions can also sometimes cause heart palpitations:

When to see your GP

You don't usually need to see your GP if the palpitations pass quickly and occur only occasionally. They're unlikely to be caused by a serious problem and probably won't need treatment.

But it's a good idea to contact your GP if:

  • the palpitations last a long time, don't improve or get worse
  • you have a history of heart problems
  • you're concerned about the palpitations

To help determine the cause, your GP may:

If you can't have an ECG at your GP surgery or your doctor wants to arrange heart monitoring over a longer time period, you may be referred for tests at a local hospital.

When to get emergency help

Call 999 for an ambulance or visit your nearest accident and emergency (A&E) department ↗ if you have heart palpitations and any of the following symptoms:

These symptoms could indicate a serious or potentially life-threatening heart problem that should be checked by a doctor as soon as possible.
