17643 Wolff Parkinson White Syndrome Wpw

Overview

Wolff-Parkinson-White (WPW) syndrome is a heart condition you are born with. In a normal heart, electrical signals follow one main pathway to control the heartbeat. In WPW, there is an extra electrical pathway. This extra pathway can cause the heart to beat very fast at times, sometimes without warning.

WPW is a relatively uncommon heart condition. It is found in about 1 to 3 in every 1,000 people.

WPW can affect anyone of any age, but symptoms often first appear in children, teenagers, or young adults. Some people find out they have it only when they have a heart tracing test for another reason.

Symptoms

Common symptoms

• A feeling that your heart is racing, fluttering, or skipping beats
• Dizziness or light-headedness
• A feeling of fainting (near-fainting) or actually fainting
• Shortness of breath, especially during an episode
• Mild chest discomfort or a feeling of tightness
• Anxiety or a sense of unease during fast heartbeats

Symptoms in children

• Fast breathing or difficulty feeding in babies
• Looking pale or sweaty
• Irritability or unusual tiredness
• Fainting or seeming limp during a fast heartbeat episode

Symptoms in older adults

• Fainting or falls without a clear cause
• Confusion or feeling unusually weak
• Sudden shortness of breath
• Chest pain or pressure during a fast heartbeat

Causes

Main causes

• WPW is caused by an extra electrical pathway in the heart that is present from birth.
• In a normal heart, electrical signals travel through a single route to make the heart beat in a coordinated way. In WPW, the extra pathway can create a 'short circuit' that makes the heart beat very fast.

Risk factors

• A family member with WPW or another heart rhythm problem
• Certain congenital heart conditions (heart problems present at birth)
• Some genetic conditions associated with heart rhythm issues

When to see a doctor

See a doctor urgently if:

• If you have frequent or prolonged episodes of a racing heartbeat
• If you faint or nearly faint during an episode
• If you have chest pain, shortness of breath, or dizziness that worries you

Book a routine appointment if:

• If you notice occasional heart palpitations and have not been checked
• If you have a family history of WPW or sudden unexplained heart problems
• If you already know you have WPW and your symptoms change

Diagnosis

A doctor may suspect WPW after listening to your symptoms and doing a physical check. The main way to diagnose it is with an electrocardiogram (ECG), which records the electrical activity of your heart.

Tests that may be done

• Electrocardiogram (ECG) – a quick and painless test that shows the heart's electrical pattern. In WPW, a specific pattern is often seen.
• Ambulatory monitor (Holter monitor) – a portable ECG you wear for 24 hours or longer to capture heartbeats during normal activities and symptoms.
• Event recorder – a small device you carry for a few weeks, and you press a button when you feel symptoms to record your heart rhythm at that moment.
• Electrophysiology study (EP study) – a test done in a hospital where thin wires are placed in the heart to map its electrical pathways in detail.

What to expect at your appointment

If your doctor thinks you may have WPW, they will likely refer you to a heart specialist (cardiologist). The specialist will review your ECG and may arrange additional monitoring. Diagnosis is usually straightforward, and your doctor will explain exactly what the findings mean for you.

Treatment

Treatment for WPW depends on your age, how often you have symptoms, and the findings from your heart tests. Some people need no treatment at all. Others may benefit from medications to control the heart rate or a procedure to remove the extra pathway.

Self-care at home

• Learn simple techniques, such as gentle breathing or coughing, that doctors may teach you to help slow a fast heartbeat when it starts.
• Keep a diary of your symptoms, noting when they happen and what you were doing.
• Avoid known triggers if they apply to you, such as extreme caffeine intake or sleep deprivation.

Medical treatments

Medications may be used to reduce the frequency of fast heartbeats or to slow the heart rate during an episode. These medicines are sometimes called antiarrhythmic drugs. Your doctor will decide which type, if any, is appropriate for you based on your specific situation. They will always explain the benefits and possible side effects, and they will not prescribe any medication without discussing it with you first.

When is surgery considered?

A procedure called catheter ablation is a common and often curative treatment for WPW. A specialist guides a thin tube through a blood vessel to your heart and uses heat or cold to carefully destroy the extra electrical pathway. This is usually done under local anaesthetic and sedation, and most people go home within a day or two.

Living with this condition

For most people, WPW does not prevent a full, active life. You can go to school, work, exercise, and enjoy normal activities. Knowing what your symptoms feel like — and having a plan for what to do when they happen — can give you confidence. Some people choose to carry a card or wear a medical alert bracelet saying they have WPW, especially if they have episodes that cause fainting.

Lifestyle tips

• Stay hydrated, as dehydration can sometimes trigger palpitations.
• Try to keep stress levels in check with relaxation, breathing exercises, or mindfulness.
• Avoid recreational drugs and limit heavy alcohol intake, as these can provoke abnormal heart rhythms.
• If you notice a pattern after certain foods or drinks, such as very high-caffeine energy drinks, consider cutting back.

Diet and exercise

A heart-healthy diet with plenty of vegetables, fruits, whole grains, and lean proteins is good for everyone. Regular exercise is generally safe and beneficial for people with WPW, but in some cases a doctor may recommend tests before starting competitive sports. Always ask your healthcare team for advice that fits your personal risk level.

Mental health and emotional wellbeing

Living with a condition that can cause sudden heart racing may lead to anxiety or fear of the next episode. This is completely understandable. It can help to talk about your feelings, learn relaxation techniques, and remember that WPW is treatable. If anxiety feels overwhelming, mention it to your doctor — they can offer support and, if appropriate, refer you to a counsellor or psychologist.

Prevention

WPW cannot be prevented because it is a structural difference in the heart that is present from birth. However, you can reduce the chance of triggering an episode by avoiding known triggers and keeping generally healthy. The focus is on managing the condition, not preventing it from developing.

Complications

If left untreated

• Frequent episodes of very fast heartbeats that interfere with daily life
• Fainting or falls caused by low blood pressure during a fast heartbeat
• In rare cases, a very rapid heart rhythm that can lead to a cardiac arrest (when the heart stops pumping blood properly)

Long-term outlook

The outlook for WPW is very good. Most people with WPW do not develop serious complications, and many do not even need treatment. For those who do, catheter ablation successfully cures the extra pathway in the vast majority of cases. With proper assessment and follow-up, you can expect to live a long, full, and active life.
