Preparing for ablation for arrhythmia
Informed by recognized medical guidance
Overview
Ablation for arrhythmia is a procedure that uses energy to destroy a tiny area of heart tissue causing an irregular heartbeat. It helps restore a normal heart rhythm.
Key facts
- The procedure is minimally invasive, meaning it uses small cuts and a thin tube called a catheter.
- It is a common and effective treatment for many types of arrhythmia.
- You will be awake but given medicine to help you relax during the procedure.
Yes, this procedure is performed frequently for people with arrhythmias that do not improve with medications or lifestyle changes.
It is used for people of all ages who have certain types of arrhythmia, such as atrial fibrillation, supraventricular tachycardia, and others. Your doctor will decide if it is right for you.
Symptoms
- Chest pain or pressure that lasts more than a few minutes
- Severe shortness of breath
- Fainting or passing out
- Sudden weakness or numbness on one side of the body or face (signs of stroke)
- ⚠Heart palpitations that come with dizziness or fainting
- ⚠Unusual tiredness that does not go away
- ⚠Swelling in your legs or ankles
Common symptoms
- A feeling that your heart is skipping beats, fluttering, or beating too fast
- Dizziness or lightheadedness
- Shortness of breath
- Chest discomfort or tightness
Symptoms in children
- Children may have the same symptoms as adults, but they might not complain of them. Instead they may seem tired, irritable, or have trouble keeping up with friends.
Symptoms in older adults
- Older adults may feel a sudden, fast or irregular heartbeat, fatigue, or fainting spells. They are also at higher risk for stroke if the arrhythmia is untreated.
Causes
Main causes
- Scar tissue from a previous heart attack or heart surgery
- High blood pressure that puts extra strain on your heart
- Heart muscle disease (cardiomyopathy)
- Thyroid problems or other hormonal imbalances
- Excessive alcohol or caffeine use
Risk factors
- Age (over 60)
- Family history of heart rhythm problems
- Obesity
- Sleep apnea
- Diabetes
When to see a doctor
See a doctor urgently if:
- If you have chest pain, fainting, or severe difficulty breathing, call your local emergency number immediately.
Book a routine appointment if:
- If you notice occasional heart fluttering or a fast heartbeat that comes and goes, make an appointment with your doctor.
Diagnosis
Your doctor will start by asking about your symptoms and medical history, and listen to your heart. They will order tests to see how your heart beats over time.
Tests that may be done
- Electrocardiogram (ECG or EKG) – records your heart’s electrical activity at a single moment
- Holter monitor – a portable device you wear for 24 to 48 hours to record your heart rhythm
- Event recorder – a device you wear for weeks to capture occasional symptoms
- Echocardiogram – an ultrasound of your heart to check its structure
What to expect at your appointment
Your doctor will explain the results and whether ablation might be a good option. You may also have to stop some medicines before the procedure. They will give you specific instructions.
Treatment
Treatment for arrhythmia starts with lifestyle changes and medicines. If those do not work, doctors may recommend catheter ablation. This is a procedure where a thin tube is guided through a blood vessel to your heart to fix the electrical problem.
Self-care at home
- Avoid triggers like too much caffeine, alcohol, or illegal drugs
- Get enough sleep and manage stress
- Keep a log of your symptoms to share with your doctor
Medical treatments
Medicines can help control the rate or rhythm of your heart. They are usually the first step in treatment. Your doctor will choose the safest one for you. Never change or stop your medicines without talking to your doctor first.
When is surgery considered?
Ablation is a type of minimally invasive surgery. It is considered when medicines do not control your symptoms or cause side effects. Open-heart surgery is rarely needed for arrhythmia, but may be done during other heart surgeries.
Living with this condition
Before ablation, you may need to adjust your daily activities to avoid triggering symptoms. After a successful ablation, many people return to normal life within a few days, but you may have some bruising or soreness at the catheter site.
Lifestyle tips
- Stay active but learn the level that is safe for you – ask your doctor
- Avoid excessive alcohol and caffeine
- Manage your blood pressure and diabetes if you have them
Diet and exercise
Eat a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins. Exercise like walking is safe for most people, but talk to your doctor before starting a new program.
Mental health and emotional wellbeing
Living with an abnormal heart rhythm can cause anxiety or stress. It is normal to worry. Share your feelings with your doctor or a counsellor. If you are having thoughts of harming yourself, reach out to a crisis support line immediately.
Prevention
Arrhythmia cannot always be prevented, but you can lower your risk by controlling high blood pressure, avoiding stimulants, staying at a healthy weight, and managing stress.
Vaccines
Stay up to date with vaccines, including the flu shot, as infections can sometimes trigger arrhythmias.
Screening programmes
If you have risk factors like a strong family history or other heart conditions, your doctor may recommend regular check-ups. There is no routine screening for arrhythmia for everyone.
Complications
If left untreated
- Stroke – when the heart does not pump properly, blood can pool and form clots that travel to the brain
- Heart failure – the heart may become weak over time from beating too fast
- Worsening symptoms that make daily life hard
Long-term outlook
Ablation is very safe and effective for many people. About 7 out of 10 people have no more symptoms after one procedure. Even if it does not completely fix the rhythm, it often makes symptoms much better. With proper care and follow-up, most people live full, active lives.
