As an FCA-authorised private medical insurance broker that has helped arrange over 750,000 policies, WeCovr understands the UK healthcare landscape. This guide explains cardioversion for heart rhythm problems, what to expect during recovery, and how private health cover can provide fast access to this vital treatment.
WeCovr explains cardioversion, recovery, and PMI cover
A diagnosis of a heart rhythm problem can be unsettling. You may be experiencing symptoms like palpitations, breathlessness, or dizziness, and your doctor might mention a procedure called 'cardioversion'. But what exactly is it, and what does it involve?
In this comprehensive guide, we'll break down everything you need to know about cardioversion. We’ll cover the different types, the conditions it treats, what to expect before, during, and after the procedure, and crucially, how private medical insurance in the UK can help you access this treatment quickly.
What is Cardioversion? A Simple Guide to Resetting Your Heart
Think of your heart's natural pacemaker as a finely tuned orchestra conductor, ensuring every part beats in perfect time. When you have a heart rhythm problem (an arrhythmia), it's as if the orchestra has lost its timing, leading to a chaotic, inefficient rhythm.
Cardioversion is a medical procedure designed to restore your heart's normal rhythm. It's like pressing a 'reset' button. By delivering a controlled electric shock or using medication, doctors can interrupt the abnormal electrical signals and allow your heart's natural pacemaker to take over again.
It's a common and highly effective treatment, particularly for conditions like Atrial Fibrillation (AFib), the most common type of arrhythmia. According to the British Heart Foundation, around 1.5 million people in the UK are living with AFib, and cardioversion is a key tool in managing the condition and improving quality of life.
Electrical vs. Pharmacological Cardioversion: What's the Difference?
There are two main ways to perform a cardioversion. The method your consultant cardiologist recommends will depend on your specific condition, your overall health, and the urgency of the situation.
-
Electrical Cardioversion: This is the most common type. It involves delivering a quick, controlled electric shock to your chest through pads or paddles. You will be given a short-acting anaesthetic or heavy sedation, so you'll be asleep and won't feel any pain during the procedure. It's very fast, with the shock itself lasting less than a second.
-
Pharmacological (Chemical) Cardioversion: This method uses anti-arrhythmic medicines to restore a normal heart rhythm. The medication is usually given through a drip in your arm (intravenously) while you are monitored in a hospital. This process takes longer than an electrical cardioversion—from a few minutes to several hours—for the heart to return to a normal rhythm.
Here’s a simple breakdown of the key differences:
| Feature | Electrical Cardioversion | Pharmacological Cardioversion |
|---|---|---|
| Method | Controlled electric shock | Anti-arrhythmic medication (IV drip) |
| Anaesthesia | Yes, short-acting general anaesthetic | No, but you will be monitored closely |
| Duration | Very fast (shock is <1 second) | Slower (minutes to hours) |
| Success Rate | Generally higher (often over 90%) | Varies depending on the medication used |
| Best For | Urgent situations or when medication fails | Less urgent cases, or for certain patients |
| Setting | Hospital procedure room | Hospital ward or A&E |
Your doctor will discuss which option is best for you, explaining the pros and cons of each in your personal situation.
Common Heart Rhythm Problems That May Require Cardioversion
Cardioversion is used to treat several types of tachyarrhythmias, which are abnormally fast heart rhythms. The most common include:
- Atrial Fibrillation (AFib): This is by far the most frequent reason for cardioversion. In AFib, the upper chambers of the heart (the atria) beat chaotically and irregularly, out of sync with the lower chambers (the ventricles). This can cause palpitations, shortness of breath, and increases the risk of stroke.
- Atrial Flutter: This is similar to AFib, but the abnormal rhythm in the atria is more organised and regular, just very fast. The symptoms are similar to AFib.
- Supraventricular Tachycardia (SVT): A very fast but regular heartbeat that originates in the atria.
- Ventricular Tachycardia (VT): A more serious, fast rhythm that starts in the ventricles. If unstable and causing severe symptoms, it requires immediate emergency cardioversion.
The Cardioversion Procedure: A Step-by-Step Walkthrough
Knowing what to expect can significantly reduce any anxiety you might feel about the procedure. Here’s a typical step-by-step guide for an electrical cardioversion, the most common type.
- Preparation: You'll be asked not to eat or drink for several hours before the procedure. This is a standard safety measure for any procedure involving anaesthesia.
- Arrival at Hospital: You'll be admitted to a ward or a day-case unit. A nurse will check your blood pressure and heart rate and may take a blood sample. A thin plastic tube (a cannula) will be inserted into a vein in your arm or hand.
- Anticoagulation: Because arrhythmias can cause blood clots to form in the heart, there's a small risk a clot could be dislodged during cardioversion and cause a stroke. To prevent this, your doctor will ensure you have been taking blood-thinning medication (anticoagulants) for at least three to four weeks beforehand.
- The Procedure Room: You'll be taken to the procedure room, which looks similar to a small operating theatre. You will lie on a bed, and staff will attach several monitoring devices, including ECG electrodes to monitor your heart, a blood pressure cuff, and a pulse oximeter on your finger to check oxygen levels.
- Anaesthesia: The anaesthetist will administer the anaesthetic through the cannula in your arm. You will fall asleep very quickly and will not be aware of what happens next.
- The Shock: Once you are asleep, the cardiologist will place large adhesive pads (defibrillator pads) on your chest and back. They will deliver a precisely timed, low-energy electric shock. The shock momentarily stuns the heart's electrical system, stopping the abnormal rhythm and allowing the normal one to restart.
- Waking Up: The entire procedure is very quick. You'll wake up a few minutes later in a recovery area. You may feel a little groggy from the anaesthetic, but this will wear off quickly.
A pharmacological cardioversion is simpler. You will be on a hospital ward, connected to a heart monitor, and the medication will be given slowly through the cannula in your arm. Staff will monitor you continuously until your heart rhythm returns to normal.
Life After Cardioversion: Recovery, Side Effects, and Long-Term Outlook
Recovery from a cardioversion is usually very straightforward.
Immediately After the Procedure:
- You will be monitored for a few hours in a recovery area.
- Most people can go home the same day.
- Because you've had an anaesthetic, you must not drive for at least 24 hours. You'll need someone to take you home and ideally stay with you overnight.
- You may feel tired for the rest of the day, so plan to rest.
Common Side Effects:
- Skin irritation: The most common side effect is some redness or soreness on your chest where the pads were placed, a bit like a mild sunburn. Your doctor may recommend a soothing cream.
- Tiredness: Feeling weary for a day or two is normal.
- Chest muscle ache: Some people experience a slight ache in their chest muscles, which resolves quickly.
Long-Term Outlook: Cardioversion can be very successful in the short term. However, it doesn't cure the underlying cause of the arrhythmia. For many people, particularly with AFib, the abnormal rhythm can return weeks, months, or even years later.
Your doctor will discuss a long-term management plan, which may include:
- Continuing anticoagulants to prevent strokes.
- Taking medication (like beta-blockers or calcium channel blockers) to control your heart rate.
- Lifestyle changes to improve your heart health.
- Considering other procedures like a catheter ablation if the arrhythmia keeps coming back.
Understanding the Risks of Cardioversion
Cardioversion is a very safe and routine procedure, but like any medical treatment, it has some small risks. Your cardiologist will ensure you understand these before you consent to the treatment.
- Stroke: This is the most serious risk, but it is rare (less than 1 in 100) if you have been taking your blood-thinning medication correctly for several weeks beforehand.
- Skin Burns: Minor burns or soreness from the electrode pads can occur but usually heal quickly.
- Ineffective Procedure: Sometimes the cardioversion doesn't work, and the abnormal rhythm continues.
- Rhythm Returns: The normal rhythm may only last for a short time before the arrhythmia comes back.
- Other Arrhythmias: Very rarely, the procedure can trigger a different, slower heart rhythm that might require a pacemaker, though this is uncommon.
Cardioversion on the NHS vs. Going Private
Both the NHS and the private sector offer excellent standards of care for cardioversion. The main difference comes down to speed of access and the patient experience.
According to the latest NHS England data, waiting lists for elective procedures remain a significant challenge. The target is for 92% of patients to wait no more than 18 weeks from referral to treatment. However, for cardiology, many patients face much longer waits, first for a consultation with a specialist and then for the procedure itself.
This is where private medical insurance (PMI) can make a profound difference.
| Feature | NHS Pathway | Private Pathway (with PMI) |
|---|---|---|
| Referral | GP refers you to a local NHS cardiologist. | GP gives you an open referral to a private cardiologist. |
| Waiting Time | Can be many months for consultation and procedure. | Typically days or weeks for consultation and procedure. |
| Choice of Specialist | You are seen by the on-duty team at your local hospital. | You can choose your consultant and hospital from your insurer's approved list. |
| Hospital Stay | Likely on a general cardiology ward with other patients. | Private room with en-suite facilities, more flexible visiting hours. |
| Continuity of Care | You may see different doctors at various stages. | You will be under the care of your chosen consultant throughout. |
| Cost | Free at the point of use. | Covered by your private health cover (subject to policy limits and excess). |
For a condition like AFib, which can cause debilitating symptoms and anxiety, the ability to bypass long waiting lists and receive treatment quickly is a major advantage of having private health cover.
How Private Medical Insurance (PMI) Covers Cardioversion in the UK
If you develop a heart rhythm problem after taking out a PMI policy, cardioversion is exactly the type of acute care that private health cover is designed for. It's a specialist-led procedure to investigate and treat a new medical condition, aiming to return you to your previous state of health.
However, there is one crucial rule to understand.
The Golden Rule: Acute vs. Chronic and Pre-existing Conditions
Standard private medical insurance UK policies are designed to cover acute conditions that begin after your policy starts. They do not cover chronic conditions or pre-existing conditions.
- Acute Condition: A disease, illness, or injury that is likely to respond quickly to treatment and return you to the health you were in before it started (e.g., AFib that can be treated with cardioversion).
- Chronic Condition: A condition that has no known cure and requires ongoing or long-term monitoring and management (e.g., high blood pressure, diabetes, or AFib that becomes persistent and is managed with medication long-term).
- Pre-existing Condition: Any illness or symptom you had, or received advice or treatment for, in the years before your policy began (typically the last 5 years).
What this means for cardioversion:
- Covered: If you buy a PMI policy and are later diagnosed with AFib for the first time, your diagnostic tests, consultations, and a subsequent cardioversion would almost certainly be covered.
- Not Covered: If you have already been diagnosed with AFib, or have had symptoms of it before you took out the policy, it will be considered a pre-existing condition and excluded from cover.
This is the single most important principle of UK private health insurance. As an expert PMI broker, WeCovr always ensures our clients understand this distinction to avoid any surprises when they need to make a claim.
How to Claim for Cardioversion on Your PMI Policy
If you develop symptoms like palpitations and need to use your insurance, the process is simple:
- Visit Your GP: Your GP will assess you. If they suspect a heart rhythm problem, they will refer you to a cardiologist. Ask for an 'open referral' letter.
- Contact Your Insurer: Call your PMI provider's claims line. Tell them your symptoms and that your GP has referred you.
- Get Pre-authorisation: Your insurer will pre-authorise your initial consultation with a specialist from their approved list.
- See the Specialist: The cardiologist will conduct tests (like an ECG or heart monitor) to diagnose the problem.
- Authorise Treatment: If the specialist recommends a cardioversion, they will provide a treatment plan and a procedure code. You or their secretary will pass this to your insurer, who will then pre-authorise the procedure.
- Receive Treatment: You can then book your procedure at the approved private hospital. The hospital and consultant will bill your insurer directly. You will only need to pay any excess on your policy.
What to Look for in a PMI Policy for Cardiac Health
When choosing a policy, look for a comprehensive plan that includes:
- Full inpatient and day-patient cover: This ensures the hospital costs for the cardioversion procedure are paid in full.
- Full cover for specialist fees: This covers the fees for your cardiologist and anaesthetist.
- Good outpatient cover: Check the limit for pre-procedure consultations and diagnostic tests (like ECGs, echocardiograms, and 24-hour heart monitors). A generous outpatient limit is essential.
- A comprehensive hospital list: Ensure the policy gives you access to high-quality local hospitals with excellent cardiology departments.

Enhancing Your Heart Health: Lifestyle Tips for Prevention
While you can't always prevent an arrhythmia, a heart-healthy lifestyle can significantly reduce your risk and support your recovery after a procedure like cardioversion.
- Diet: Follow a balanced diet low in saturated fat, salt, and sugar. The Mediterranean diet, rich in fruits, vegetables, fish, and whole grains, is excellent for heart health.
- Exercise: Aim for at least 150 minutes of moderate-intensity activity (like brisk walking or cycling) per week, as recommended by the NHS.
- Weight Management: Maintaining a healthy weight reduces the strain on your heart.
- Limit Alcohol: Excessive alcohol is a known trigger for AFib. Stick within the recommended guidelines.
- Quit Smoking: Smoking is one of the worst things you can do for your heart.
- Manage Stress: Chronic stress can affect your heart. Practice relaxation techniques like mindfulness, yoga, or deep breathing.
