WeCovr explains Supraventricular Tachycardia and private cardiology support
That sudden, unnerving sensation of your heart racing for no apparent reason can be frightening. If you've experienced this, you might have encountered an episode of Supraventricular Tachycardia, or SVT. While often not life-threatening, it can be disruptive and concerning, prompting many to wonder about their healthcare options beyond the NHS.
This comprehensive guide explains what SVT is, how it's diagnosed and treated, and the pivotal role private medical insurance can play in accessing fast, specialist cardiology care in the UK.
What is Supraventricular Tachycardia (SVT)?
In simple terms, SVT is an abnormally fast heart rhythm. It's caused by a problem with the heart's electrical system, originating in the upper chambers (the atria).
Think of your heart's electrical system as a perfectly timed orchestra. A natural pacemaker, called the sinoatrial node, sends out regular electrical signals to make your heart contract and pump blood. In SVT, a 'short circuit' or an extra electrical pathway can interfere with this rhythm, causing the heart to suddenly beat very quickly – often between 140 and 220 beats per minute, or even faster.
This isn't the same as a fast heart rate from exercise or stress, which is a normal response. An SVT episode can start and stop abruptly, lasting for seconds, minutes, or in some cases, hours.
Key Symptoms of an SVT Episode
When your heart beats this fast, it can't fill with blood properly between beats, which can lead to a range of symptoms:
- Palpitations: A feeling of a fluttering, pounding, or racing heart.
- Dizziness or Light-headedness: Reduced blood flow to the brain can cause you to feel faint.
- Shortness of Breath: A sensation of not being able to get enough air.
- Chest Discomfort or Tightness: A feeling of pressure in the chest.
- Anxiety: The sudden onset of symptoms can naturally cause panic or anxiety.
- Tiredness: Feeling exhausted after an episode.
SVT can affect anyone at any age, including children, but it's most common in younger people and affects women more frequently than men. According to the British Heart Foundation, arrhythmias (abnormal heart rhythms) like SVT are a significant health issue in the UK, affecting more than 2 million people.
Diagnosing SVT: The NHS vs. Private Pathways
If you experience symptoms of SVT, the first step is always to see your GP. From there, your journey to a diagnosis can follow two different paths: the NHS or a private route. The main difference? Speed and choice.
The NHS Pathway
- GP Appointment: You'll describe your symptoms to your GP. They may perform a simple electrocardiogram (ECG) in the surgery if the equipment is available.
- Referral: If SVT is suspected, your GP will refer you to an NHS cardiologist for specialist assessment.
- Waiting List: This is where delays often occur. According to NHS England data, waiting times for a first consultant appointment can be lengthy. In late 2024, millions of people were on NHS waiting lists, with cardiology being one of the specialisms under pressure. The median wait time for treatment can be several months.
- Diagnostic Tests: Once you see the cardiologist, they will order tests to confirm the diagnosis. This may involve another wait.
- Treatment Plan: Following diagnosis, you'll be placed on a waiting list for any necessary treatment, such as catheter ablation.
The Private Pathway (with or without PMI)
- GP Referral (or Self-Referral): You can ask your GP for a private referral. Some private medical insurance policies and private hospitals also allow you to self-refer to a specialist.
- Cardiologist Appointment: You can typically book an appointment to see a consultant cardiologist of your choice within days or a week.
- Rapid Diagnostics: Diagnostic tests are usually carried out very quickly, sometimes even on the same day as your consultation.
- Prompt Treatment: If treatment is needed, it can be scheduled at your convenience, often within a few weeks.
This speed is the primary reason many people consider private healthcare. For a condition like SVT, which can cause significant anxiety and disruption to daily life, waiting months for a diagnosis and cure can be incredibly stressful.
NHS vs. Private Pathway for SVT: A Comparison
| Feature | NHS Pathway | Private Pathway |
|---|
| GP Appointment | Standard wait times apply | Can use NHS GP for a private referral |
| Seeing a Cardiologist | Weeks or months | Typically within a few days to a week |
| Diagnostic Tests | Further waiting lists may apply | Often done on the same day or within a week |
| Choice of Specialist | Limited to who is available at your local NHS trust | You can choose your consultant and hospital |
| Treatment Schedule | Added to an NHS waiting list | Scheduled promptly at your convenience |
| Environment | NHS hospital ward | Private room, often with hotel-like amenities |
| Cost | Free at the point of use | Funded by you or your private health cover |
Understanding the Key Diagnostic Tests for SVT
Whether on the NHS or privately, a cardiologist will use specific tests to capture the abnormal rhythm and diagnose SVT.
- Electrocardiogram (ECG): This is a simple, painless test that records the electrical activity of your heart. It's very effective if you are having an SVT episode during the test.
- Holter Monitor (Ambulatory ECG): If your episodes are infrequent, you may be asked to wear a small, portable ECG device for 24-48 hours (or longer). This records your heart's activity as you go about your daily life, increasing the chance of capturing an episode.
- Event Recorder: Similar to a Holter monitor, but you might wear it for a week or more and press a button to record your heart rhythm when you feel symptoms.
- Echocardiogram: An ultrasound scan of the heart. It doesn't diagnose SVT itself but checks the structure and function of your heart muscle and valves to ensure there are no other underlying problems.
- Electrophysiological (EP) Study: A more invasive test, usually done just before a treatment called catheter ablation. A specialist guides thin wires through a vein in your groin up to your heart to map its electrical system precisely and pinpoint the source of the SVT.
Private medical insurance with good outpatient cover is essential for ensuring these diagnostic tests are covered without you having to pay out of pocket.
Private Treatment Options for SVT in the UK
Once diagnosed, there are several highly effective treatments for SVT. Accessing them privately means you can get back to living your life without the constant worry of another episode.
1. Vagal Manoeuvres
These are simple physical techniques you can be taught to do yourself to try and stop an episode. They work by stimulating the vagus nerve, which can help to slow the heart rate. Examples include:
- The Valsalva Manoeuvre: Pinching your nose, closing your mouth, and trying to forcefully breathe out (like blowing up a balloon).
- Gently massaging the carotid artery in your neck (only do this if a doctor has shown you how and confirmed it's safe for you).
- Splashing your face with ice-cold water.
These are a first-line response, not a cure.
2. Medication
Drugs can be used to stop an episode in progress or taken daily to prevent them from happening.
- Adenosine: Given intravenously in a hospital to rapidly stop an SVT episode.
- Beta-blockers & Calcium Channel Blockers: Taken as daily tablets to control the heart rate and reduce the frequency of episodes.
Medication can be effective but often requires long-term use and can have side effects.
3. Catheter Ablation
For many people, catheter ablation is the preferred treatment as it offers a permanent cure. It has a very high success rate (often over 95%) for most types of SVT.
What happens during a catheter ablation?
- It's a minimally invasive procedure performed by a specialist cardiologist called an electrophysiologist.
- You'll be given a local anaesthetic and a sedative to make you comfortable.
- The specialist inserts thin, flexible tubes called catheters into a vein, usually in your groin.
- Using X-ray imaging, they guide these catheters to your heart.
- They use the catheters to map the heart's electrical signals and find the exact location of the 'short circuit' causing the SVT.
- Once found, they deliver a burst of radiofrequency energy (heat) or cryoenergy (freezing) to the tiny area of heart tissue, destroying the faulty pathway.
Recovery is usually very quick, with most people returning to normal activities within a few days. The main benefit is that, for the vast majority of patients, it's a one-off procedure that cures the SVT for good.
Private SVT Treatment Options at a Glance
| Treatment | Description | Best For | Typical Private Success Rate |
|---|
| Vagal Manoeuvres | Physical actions to stimulate the vagus nerve and slow the heart. | Stopping mild, infrequent episodes at home. | Variable, not a cure. |
| Medication | Daily tablets (e.g., beta-blockers) or IV drugs in hospital. | Preventing frequent episodes or for those who don't want ablation. | Good for control, but not a cure. |
| Catheter Ablation | A keyhole procedure to find and destroy the faulty electrical pathway. | A permanent cure for most types of SVT. | >95% for common SVT types. |
| Cardioversion | An electrical shock delivered to the chest to reset the heart's rhythm. | Stopping a prolonged episode that doesn't respond to other treatments. | Very high for stopping an active episode. |
The Critical Role of Private Medical Insurance (PMI) for SVT
Private medical insurance can be your key to unlocking this fast, high-quality care. However, it is vital to understand how insurance policies work, particularly regarding heart conditions.
The Golden Rule: Pre-existing and Chronic Conditions
Standard UK private medical insurance is designed to cover acute conditions that arise after you take out your policy.
- An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Many cases of SVT, especially those curable with ablation, fit this definition.
- A pre-existing condition is any health issue for which you have had symptoms, medication, advice, or treatment before your policy starts.
- A chronic condition is one that is long-lasting and cannot be cured, only managed (e.g., high blood pressure, diabetes).
Crucially, standard PMI policies do not cover pre-existing or chronic conditions. If you have already been diagnosed with SVT or have sought medical advice for palpitations before buying a policy, it will be excluded from cover.
Real-Life Scenarios
- Covered: Aisha, 35, has had a PMI policy for two years. She suddenly experiences her first-ever episode of racing heart and dizziness. Her GP suspects SVT. Her private medical insurance will cover her private cardiology consultation, diagnostic tests, and a catheter ablation because it is a new, acute condition that began after her policy started.
- Not Covered: Ben, 40, was diagnosed with SVT three years ago and manages it with medication. He now decides to buy private health cover, hoping to get a private ablation. His SVT will be considered a pre-existing condition and will be excluded from his new policy. The policy will still cover him for new, unrelated conditions.
Understanding Underwriting
When you apply for PMI, the insurer will 'underwrite' your policy to decide what they will and won't cover.
- Moratorium Underwriting: This is the most common type. The policy automatically excludes any condition you've had in the 5 years before the policy start date. However, if you then go for a continuous 2-year period after your policy begins without any symptoms, treatment, or advice for that condition, the insurer may reinstate cover for it.
- Full Medical Underwriting (FMU): You provide your full medical history via a questionnaire. The insurer then assesses it and tells you upfront exactly what is excluded from your policy, which is usually permanent.
Navigating these rules can be complex. An expert PMI broker like WeCovr can provide invaluable, free advice, helping you understand the small print and find the best PMI provider and policy for your personal circumstances.
How Much Does Private SVT Treatment Cost Without Insurance?
The cost of private healthcare highlights the value of a good insurance policy. Without cover, you would be paying for every consultation, scan, and procedure yourself.
Here are some estimated costs for private SVT care in the UK for 2025. Prices vary significantly based on the hospital, consultant, and location (e.g., London is more expensive).
| Service | Estimated Private Cost Range (Without Insurance) |
|---|
| Initial Cardiology Consultation | £250 – £400 |
| Electrocardiogram (ECG) | £100 – £200 |
| 24-Hour Holter Monitor | £350 – £600 |
| Echocardiogram | £450 – £800 |
| Catheter Ablation Procedure | £8,000 – £15,000+ |
As you can see, the cost of a definitive treatment like catheter ablation can be substantial, making comprehensive private medical insurance UK a very sound financial decision for those who can access it.
Lifestyle and Wellness: Supporting Your Heart Health
While medical treatment is key for SVT, a heart-healthy lifestyle can help manage symptoms and improve your overall wellbeing.
- Know Your Triggers: Many people find that certain things can trigger an SVT episode. Common culprits include caffeine, alcohol, lack of sleep, stress, and some over-the-counter cold remedies. Keeping a diary can help you identify yours.
- Stress Management: Since anxiety can be both a symptom and a trigger, managing stress is vital. Techniques like mindfulness, deep breathing exercises, yoga, and regular gentle exercise can be very effective.
- Diet and Nutrition: A balanced, heart-healthy diet low in processed foods, salt, and saturated fat is beneficial for everyone. Staying well-hydrated is also important. To help you on this journey, WeCovr provides customers with complimentary access to CalorieHero, our AI-powered calorie and nutrition tracking app.
- Travel with Confidence: If you have SVT, you can still travel. Just be prepared. Carry a letter from your doctor, ensure you have enough medication, and know how to perform your vagal manoeuvres.
Choosing the Right Private Health Cover
When looking for a policy, it's wise to think ahead. Even if you're in perfect health now, you want a policy that provides robust cover should a cardiac issue arise in the future.
Key things to look for:
- Comprehensive Outpatient Cover: Choose a policy with a high or unlimited outpatient limit. This ensures all your diagnostic consultations and tests will be covered without you reaching a low annual limit.
- Full Cancer Cover: While not related to SVT, this is a core benefit of all good PMI policies and a primary reason people seek cover.
- A Good Hospital List: Check that the insurer's approved hospital list includes facilities near you with renowned cardiology departments.
- Mental Health Support: Leading insurers now offer excellent mental health pathways, which can be invaluable for dealing with the anxiety that can accompany a new heart diagnosis.
Comparing the market can be daunting. As an independent broker, WeCovr works with all the UK's leading insurers, including Bupa, AXA Health, Aviva, and Vitality. We do the hard work for you, comparing policies and prices to find the best fit for your needs and budget, all at no cost to you.

Can I get private medical insurance if I already have SVT?
Generally, if you have already been diagnosed with SVT or have sought medical advice for related symptoms like palpitations, it will be considered a pre-existing condition by a new insurance policy. Standard UK private medical insurance does not cover pre-existing conditions. However, the policy would still cover you for any new, unrelated acute conditions that arise after you join.
Does private medical insurance cover catheter ablation for SVT?
Yes, absolutely. If your SVT symptoms develop for the first time *after* your private medical insurance policy has started, then catheter ablation is a standard procedure that is typically covered by comprehensive plans. It is considered a curative treatment for an acute condition, which is precisely what PMI is for. Cover is always subject to the terms and outpatient limits of your specific policy.
How quickly can I see a private cardiologist for suspected SVT?
This is one of the main benefits of private healthcare. While you might wait weeks or months for an NHS cardiology appointment, you can typically see a private consultant cardiologist within a few days to a week of getting a GP referral. Diagnostic tests are also performed much faster, meaning you get a diagnosis and a treatment plan very quickly, significantly reducing anxiety and uncertainty.
