R F Ablation Study with Mapping
RF Ablation Study with Mapping is an advanced cardiac electrophysiology procedure that precisely identifies and permanently eliminates abnormal electrical pathways causing dangerous heart rhythm disorders — offering patients a long-term cure for arrhythmias without lifelong medication.
Overview
RF Ablation with Electrophysiology Mapping uses electrode catheters guided into the heart to create a detailed 3D electrical map, pinpointing the exact abnormal tissue causing the arrhythmia before delivering precise radiofrequency energy to permanently ablate it and restore a normal heart rhythm. This sophisticated procedure is performed by a specialist cardiac electrophysiologist and offers cure rates exceeding 95% for common arrhythmias such as SVT and atrial flutter. For many patients, it means freedom from medications, palpitations, and the constant anxiety of unpredictable arrhythmia episodes.
Types of RF Ablation
RF Ablation is used to treat a wide range of heart rhythm disorders, and the specific technique depends on the type and location of the arrhythmia.
- SVT Ablation (supraventricular tachycardia — very high cure rates)
- WPW Syndrome Ablation (Wolff-Parkinson-White — accessory pathway elimination)
- Atrial Flutter Ablation (cavotricuspid isthmus ablation)
- Atrial Fibrillation Ablation with Pulmonary Vein Isolation
- Ventricular Tachycardia (VT) Ablation
Risk Factors of Cardiac Arrhythmia
Heart rhythm disorders can affect people of all ages and fitness levels. Identifying and managing these risk factors alongside ablation therapy gives patients the best chance of long-term arrhythmia freedom.
- Structural heart disease including cardiomyopathy or previous heart attack
- Hypertension causing atrial and ventricular remodelling
- Obstructive sleep apnoea strongly associated with atrial fibrillation
- Excessive alcohol consumption triggering arrhythmia episodes
- Hyperthyroidism causing rapid, irregular heart rhythms
- Congenital accessory electrical pathways present from birth
Cardiac Arrhythmia Symptoms
Cardiac arrhythmias can range from barely noticeable to life-disrupting. Many patients live with significant symptoms for years before discovering that RF ablation can offer a permanent solution.
- Sudden episodes of very rapid, pounding heartbeat (palpitations)
- Dizziness or near-fainting during arrhythmia episodes
- Actual fainting caused by haemodynamically significant arrhythmias
- Chest tightness or discomfort during fast heart rhythm episodes
- Breathlessness and inability to exert physically during tachycardia
- Profound fatigue lasting hours after an arrhythmia episode resolves
- Anxiety and psychological distress from unpredictable arrhythmia episodes
- Reduced quality of life and inability to exercise or work confidently

Advanced 3D electroanatomical mapping technology for sub-millimetre accuracy
Identifies and permanently eliminates the exact source of the heart rhythm disorder
High cure rates exceeding 95% for common arrhythmias such as SVT and atrial flutter
Catheter-based procedure — no open-heart surgery or general anaesthesia required
Real-time monitoring of heart rhythm and function throughout the entire procedure
Preparation Instructions
- Fast completely for 6 to 8 hours before the procedure
- Stop antiarrhythmic medications 3 to 5 days before if instructed by your electrophysiologist
- Complete all pre-procedure investigations: ECG, 24-hour Holter monitor, echocardiogram, and blood tests
- Inform your doctor of all medications, particularly blood thinners and thyroid medications
- Avoid caffeine (tea, coffee, energy drinks) for at least 48 hours before the procedure
- Arrange for a responsible adult to collect you after the procedure
- Shave the groin area on both sides as catheter access is typically via the femoral veins
- Wear comfortable, loose clothing to the hospital on the day of the procedure
The Procedure
Step-by-step guide to what you can expect during your r f ablation study with mapping procedure.
Electrophysiology Assessment and Planning
Your cardiac electrophysiologist reviews your ECG recordings, Holter monitor results, echocardiogram, and symptom history to confirm the type of arrhythmia, assess its likely origin, and plan the most precise ablation strategy to permanently cure your heart rhythm disorder.
Preparation and Sedation
You receive conscious sedation or light anaesthesia so you remain relaxed and pain-free throughout the procedure. Our team confirms fasting status, medication review (including temporary withdrawal of antiarrhythmic drugs), groin preparation, and sterile access site setup before the mapping catheters are introduced.
Creating Your Heart's Electrical Map
Multiple electrode catheters are gently positioned inside the heart through the groin veins and used alongside advanced 3D mapping technology to create a precise, colour-coded electrical map of your heart's rhythm circuits — pinpointing the exact tissue responsible for your arrhythmia with remarkable accuracy.
Triggering and Confirming the Arrhythmia
Your electrophysiologist carefully induces your arrhythmia in the controlled catheterisation lab environment using programmed electrical stimulation, confirming its exact origin point and mechanism. This crucial step ensures the ablation energy is delivered to precisely the right location.
Delivering Radiofrequency Ablation Energy
Precise radiofrequency energy is delivered through the ablation catheter to the identified abnormal tissue, creating a small, targeted scar that permanently interrupts the faulty electrical circuit. Most patients feel only a mild warmth in the chest during energy delivery, which lasts just a few seconds.
Confirming Successful Arrhythmia Elimination
After ablation, your electrophysiologist re-tests extensively to confirm the arrhythmia can no longer be triggered, the treated circuit is permanently blocked, and all other heart rhythm parameters are normal. This thorough verification gives you the best chance of long-term freedom from your arrhythmia.
What to Expect
You will receive sedation or light anaesthesia to keep you comfortable throughout the 2 to 4 hour procedure. Electrode catheters are threaded through the groin veins into the heart, an electrical map is created, and radiofrequency energy precisely eliminates the arrhythmia source. You may feel a brief warm sensation in the chest during energy delivery, which is normal. Most patients are discharged the next morning feeling significantly better.
Recovery
Rest at home for 2 to 3 days and avoid strenuous exercise for at least one week. Some occasional missed beats or brief palpitations in the first 4 to 6 weeks are normal as the heart heals. Take all prescribed medications as directed and attend your follow-up at 6 to 8 weeks so your electrophysiologist can assess long-term ablation success. Contact your doctor promptly for any return of significant palpitations, chest pain, or breathlessness.
