Heart palpitations

6-minute read

Key facts

  • Palpitations are when you have an abnormal awareness of your heart beating.
  • Palpitations are common and can affect people of all ages.
  • While most cases of palpitations are not serious, sometimes urgent medical care is needed.

What are heart palpitations?

Palpitations is the feeling of being aware of your heart beating. It can feel like your heart is beating faster or harder than usual. It can sometimes feel like your heart is:

  • having extra beats
  • missing or skipping beats
  • fluttering

Most of the time you don't notice your heartbeat, so it may come as a surprise to suddenly become aware of your heartbeat.

Palpitations are a common symptom and can affect people of all ages.

Palpitations are usually not serious. But always see your doctor if you have palpitations or feel you have an irregular heartbeat.

Call triple zero (000) if you have heart palpitations along with these symptoms:

How is the cause of heart palpitations diagnosed?

Your doctor will talk with you about your palpitations. They will ask:

  • how the palpitations start and stop (gradually or suddenly)
  • how they feel
  • how long they last
  • how often they happen
  • if anything seems to trigger your palpitations (bring them on or make them worse)
  • if anything makes your palpitations better
  • about any other symptoms you have

Your doctor will also ask about any heart conditions or other health problems you have, and about your family medical history.

Your doctor will examine you and will recommend tests, such as an electrocardiogram (ECG). This measures your heart's electrical activity.

Other tests may include:

  • blood tests
  • a Holter monitor — an ECG monitor that you wear continuously for 1 to 2 days while going about your normal activities
  • a monitor that you wear for longer periods that records episodes of palpitations
  • an echocardiogram — a special ultrasound scan of your heart

Your doctor may recommend referral to a specialist doctor for further tests.

When should I see my doctor?

While there are many causes of heart palpitations that are not serious, it's important to check with your doctor if you have this symptom.

When to seek urgent care

See your doctor urgently if you have:

  • heart palpitations that last more than a few minutes
  • frequent episodes of heart palpitations
  • a family history of heart rhythm problems

Call triple zero (000) for an ambulance if you have heart palpitations along with these symptoms:

How are heart palpitations treated?

Treatment of heart palpitations depends on:

  • what is causing them
  • how bad your symptoms are

Self-care at home

There are some things that may help with palpitations that are due to a known, non-serious cause.

  • Try sitting down or finding somewhere quiet to rest.
  • Try to 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, such as your collar button and tie.

Always see your doctor to work out the cause of your palpitations and whether medicines or other treatments are needed.

Medicines and other treatment options

If you have a heart condition like an arrhythmia, your doctor may refer you a specialist. Your doctor may recommend treatment with:

  • medicines
  • surgery
  • an implantable device

Always ask your doctor if you are concerned about your heart palpitations.

Can heart palpitations be prevented?

If you have had heart palpitations, try to avoid anything that brings them on or makes them worse. This includes:

  • caffeine
  • nicotine
  • alcohol
  • certain medicines, such as some antihistamines, antibiotics and antidepressants
  • recreational drugs
