Catheter Ablation: Treating the Source of an Abnormal Heart Rhythm
Repeated racing-heart episodes can interrupt daily life. For some rhythm disorders, ablation offers an alternative to ongoing symptoms or long-term medicine alone.
Preparing for treatment
Choosing treatment
Mapping and ablation
Monitoring
Bring recordings of the abnormal rhythm. Get clear instructions about fasting and every heart medicine. Do not stop an anticoagulant or rhythm medicine on your own.
Points to discuss
Use these points to prepare for your consultation.
- Has the abnormal rhythm been captured on an ECG?
- How often do episodes occur, and how do they affect you?
- Which medicines have you tried, and with what result?
Chest pain, fainting, severe breathlessness, stroke symptoms or uncontrolled bleeding needs emergency assessment.
About this treatment
Catheter ablation treats small areas of heart tissue that start or sustain an abnormal rhythm. Thin tubes are guided through blood vessels to the heart. The specialist maps the electrical signals before treating the target area. Techniques and expected results differ between SVT, atrial fibrillation and other rhythms.
Ask whether your rhythm diagnosis is suitable for an electrophysiology consultation.
When it may be recommended
Your assessment helps establish whether this option suits your condition and overall health.
- Selected recurrent or symptomatic SVT
- Selected symptomatic atrial fibrillation
- Other rhythm disorders after an electrical rhythm specialist’s assessment
Your care journey
Choosing treatment
The specialist compares ablation with medicines and observation for your specific rhythm.
Mapping and ablation
Anaesthesia or sedation is used as appropriate. Electrical mapping guides the treatment.
Monitoring
The team checks your rhythm and access site, then plans medicines and follow-up.
“Ask your care team to explain each step and the follow-up you will need.”
Benefits and risks
May reduce episodes and improve symptoms. Can provide lasting rhythm control for some conditions, although results vary.
Bleeding, vessel injury, infection or damage to normal electrical pathways may occur. Serious risks include stroke or heart injury. Repeat treatment or a pacemaker may sometimes be needed.
Recovery and follow-up
Allow the access site to heal and follow activity restrictions.
Palpitations may occur during healing, but persistent or severe symptoms need review. After AF ablation, the need for anticoagulation depends on your risk and specialist advice, not just how normal the pulse feels.
Chest pain, fainting, severe breathlessness, stroke symptoms or uncontrolled bleeding needs emergency assessment.
Questions for your consultation
- 1.What result is realistic for my type of rhythm?
- 2.Could I need another procedure?
- 3.Which medicines continue afterwards?
Not Sure What You Need?
Ask whether your rhythm diagnosis is suitable for an electrophysiology consultation.
