Ventricular premature beats

Overview

Ventricular premature beats (VPBs) are extra heartbeats that begin in the lower chambers of the heart (ventricles). They happen when the heart's normal rhythm is briefly interrupted by an early beat, often followed by a pause and then a stronger beat. Most people have them at some point, and they are usually harmless.

Yes, VPBs are very common. Many people experience them occasionally, especially during times of stress or after caffeine.

VPBs can affect anyone, but they are more common in older adults, people with high blood pressure or heart disease, and those who smoke or drink a lot of alcohol or caffeine.

Symptoms

Common symptoms

• A fluttering or pounding feeling in the chest (palpitations)
• A skipped beat or a sensation that the heart 'stops' briefly
• A thud or heavy beat in the chest after the pause

Symptoms in children

• Children may not feel any symptoms.
• Some children describe a fluttering or fast heartbeat.

Symptoms in older adults

• Older adults often notice palpitations more.
• They may also feel lightheaded or short of breath if VPBs are frequent.

Causes

Main causes

• Stress, anxiety, or strong emotions
• Too much caffeine, alcohol, or nicotine
• Certain medications (like cold remedies or asthma inhalers)
• Electrolyte imbalances (low potassium or magnesium)
• Heart conditions such as high blood pressure, heart attack, or heart failure

Risk factors

• Being older
• Having a history of heart disease
• Smoking or using tobacco
• Drinking a lot of alcohol
• High blood pressure
• Lack of sleep or poor sleep

When to see a doctor

See a doctor urgently if:

• Chest pain, fainting, or severe breathlessness – call your local emergency number.
• Palpitations that happen with dizziness or make you feel like you might pass out.

Book a routine appointment if:

• If you notice frequent or bothersome palpitations, make an appointment with your doctor.
• If you have a known heart condition and notice new or worsening symptoms.

Diagnosis

Your doctor will ask about your symptoms, listen to your heart, and may do tests to see how your heart beats over time.

Tests that may be done

• Electrocardiogram (ECG) – a quick test to record your heart's rhythm
• Holter monitor – a portable device you wear for 24–48 hours to capture heartbeats during normal activities
• Event monitor – a device you use for weeks to record symptoms
• Echocardiogram – an ultrasound of your heart to check its structure and function

What to expect at your appointment

These tests are painless. You may be asked to keep a diary of your symptoms. Your doctor will explain what the results mean and whether any treatment is needed.

Treatment

For most people with a healthy heart, VPBs do not need treatment. If symptoms bother you or you have an underlying heart condition, your doctor may suggest lifestyle changes or medications.

Self-care at home

• Cut back on caffeine, alcohol, and tobacco.
• Find ways to manage stress, such as deep breathing or gentle exercise.
• Get enough sleep and try to keep a regular schedule.
• Stay hydrated and eat a balanced diet with enough potassium and magnesium.

Medical treatments

If VPBs are frequent or cause symptoms, your doctor may prescribe medications to help control heart rhythm. In some cases, a procedure called catheter ablation may be used to stop the extra beats. This involves threading a thin tube to the heart to correct the area causing the problem.

When is surgery considered?

Surgery is rarely needed. If VPBs are due to a serious underlying heart condition, that condition may require surgery.

Living with this condition

Most people with VPBs live normally without restrictions. You can work, exercise, and travel as usual. If symptoms bother you, follow your doctor's advice.

Lifestyle tips

• Avoid triggers like heavy meals, too much caffeine, or late nights.
• Learn relaxation techniques to reduce stress.
• Keep a symptom diary to share with your doctor.

Diet and exercise

Eat a heart-healthy diet with plenty of fruits, vegetables, and whole grains. Stay active with moderate exercise like walking or swimming. Ask your doctor what level of activity is right for you.

Mental health and emotional wellbeing

Having palpitations can cause worry or anxiety. It helps to remember that VPBs are usually harmless. If anxiety becomes a problem, talk to your doctor or a counsellor.

Prevention

You cannot always prevent VPBs, but you can reduce your risk by avoiding triggers, managing stress, and taking care of your heart health.

Screening programmes

Routine screening is not needed for most people. If you have risk factors or symptoms, your doctor may recommend regular check-ups.

Complications

If left untreated

• In hearts that are otherwise healthy, VPBs rarely cause complications.
• If you have underlying heart disease, frequent VPBs can sometimes lead to a weakened heart muscle or a more serious abnormal rhythm.

Long-term outlook

For most people, VPBs are harmless and do not affect life expectancy. With proper management, even those with more frequent beats can live well. Your doctor can help you understand your personal situation.
