Catheter ablation is planned according to the rhythm diagnosis and the area of the heart involved. Preparation and recovery differ between simple supraventricular tachycardia ablation, atrial fibrillation ablation and ventricular arrhythmia procedures.
Before the Procedure
- Follow the fasting time and medicine plan provided by the electrophysiology team.
- Never stop an anticoagulant or antiarrhythmic medicine unless the team gives a specific instruction.
- Report fever, infection, pregnancy, kidney disease, allergies and previous contrast reactions.
- Arrange transport because driving immediately after sedation or anaesthesia is usually not appropriate.
The First Days After Ablation
- Keep the groin or wrist puncture site clean and follow the dressing instructions.
- Mild bruising or awareness of extra beats can occur; steadily increasing pain, swelling or bleeding is not expected.
- Avoid heavy lifting and strenuous exercise for the period specified by the treating team.
- Continue prescribed anticoagulant and rhythm medicines exactly as directed.
Rhythm and Follow-Up
- Early palpitations do not always mean that the ablation has failed, particularly after atrial fibrillation ablation.
- Record the time, duration and pulse during symptoms and use ECG-capable monitoring when advised.
- Attend the planned ECG, Holter or device follow-up even if you feel well.
When to Seek Emergency Help
Do not wait for an online reply
- Bleeding from the puncture site that does not stop with firm pressure
- Chest pain, severe breathlessness, fainting or stroke symptoms
- A rapidly enlarging painful groin swelling
- Persistent fast rhythm with weakness or low blood pressure
