Palpitations

Palpitations are a noticeable, unusual, or racing heartbeat, and most causes are treatable once properly diagnosed. Professor Malcolm Finlay, Consultant Cardiologist and Cardiac Electrophysiologist, investigates and treats palpitations at One Welbeck and St Bartholomew’s Hospital, London, with same-day appointments usually available.

How We Get to a Diagnosis

Listen First

A detailed history of when your palpitations happen, how they feel, and what brings them on or settles them.

Capture the Rhythm

An ECG, and where needed, a Holter monitor or implantable loop recorder, to record what's actually happening in your heart.

Explain & Treat

A clear diagnosis, explained plainly, with a treatment plan matched to the specific cause.

What Are Palpitations?

Palpitations are the sensation of your own heartbeat, whether that’s racing, pounding, fluttering, or skipping a beat.

Palpitations are extremely common and are not always a sign of a serious problem. However, because the sensation can have many different underlying causes, from harmless extra beats to a rhythm disorder needing treatment, an accurate diagnosis matters more than the symptom itself.

What Causes Palpitations?

Palpitations can be caused by heart rhythm disorders, or by non-cardiac factors such as caffeine, stress, thyroid problems or anaemia.

Atrial fibrillation, atrial flutter, SVT or other arrhythmias

Ectopic beats (occasional extra or skipped beats, usually harmless)

Caffeine, alcohol, or stimulant use

Anxiety or stress

Thyroid problems

Anaemia or dehydration

Certain medications

Professor Finlay’s role is to work out which of these applies to you, and to rule out a rhythm disorder where one isn’t present.

How Are Palpitations Diagnosed?

Diagnosis starts with an ECG and history, and moves on to further monitoring if palpitations are infrequent or weren’t captured on the first test.

ECG

A snapshot of your heart's electrical activity, done in clinic

Holter monitor

Continuous ECG recording over 24 hours to 2 weeks, for palpitations that occur every few days.

Implantable loop recorder

A long-term monitor for palpitations or blackouts that occur only occasionally.

Blood tests

To check for thyroid problems, anaemia or other contributing factors.

Echocardiogram

Where the heart's structure needs to be assessed alongside its rhythm.

Treatment Options for Palpitations

Treatment depends entirely on the cause, from simple reassurance and lifestyle changes through to catheter ablation.

Reassurance & lifestyle advice

Where palpitations are due to caffeine, stress or occasional ectopic beats

Medication

To manage an underlying rhythm disorder or its symptoms

Catheter ablation

Where an arrhythmia such as AF, atrial flutter or SVT is identified and treatment is appropriate

Treating the underlying cause

Such as thyroid treatment, where palpitations are not due to the heart's electrical system at all

When Should Palpitations Be Reviewed by a Specialist?

Palpitations that are frequent, prolonged, or accompanied by other symptoms are worth having properly assessed rather than waiting to see if they settle.

Palpitations alongside chest pain, breathlessness, dizziness or blackouts should be assessed promptly. If you are experiencing chest pain, severe breathlessness or a blackout right now, this is a medical emergency and you should call 999 or attend A&E rather than book a routine appointment.

Frequently Asked Questions About Palpitations

Are palpitations dangerous?

Most palpitations are not dangerous, particularly occasional extra beats. However, some causes, such as certain arrhythmias, do need treatment, which is why an accurate diagnosis matters.

A normal ECG only reflects the moment it was taken. If your palpitations come and go, a Holter monitor or implantable loop recorder can capture what’s happening during an actual episode.

Not necessarily. Palpitations have many possible causes, and AF is only one of them. Proper investigation is the only reliable way to know which applies to you.

Yes, stress and anxiety are common, genuine causes of palpitations. Professor Finlay’s assessment helps confirm this and rule out a rhythm disorder at the same time.
