Diagnostic Test & Treatment
Catheter Ablation
Catheter ablation is a procedure used to treat heart rhythm problems by selectively treating the small areas of heart tissue causing the abnormality. It can significantly improve, and for some conditions cure, arrhythmias such as atrial fibrillation, atrial flutter and supraventricular tachycardia.
01Why It’s Done
Dr Lee may recommend this for patients with:
- Atrial fibrillation and atrial flutter
- Supraventricular tachycardia (SVT)
- Frequent ectopic beats and ventricular tachycardia
02How It Works
- Thin catheters are threaded into the heart through small punctures in the groin.
- The area causing the abnormal rhythm is precisely mapped.
- Radiofrequency energy (heat) or cryoablation (cold) is used to treat the target tissue.
- The normal rhythm pathway is restored.
03Duration, Recovery & What To Expect
Most patients stay briefly for observation and recover within a few days. Dr Lee will provide detailed, individualised aftercare advice.

Common Questions
Frequently Asked Questions
Can catheter ablation cure my arrhythmia?
For conditions such as SVT and atrial flutter, ablation can offer a long-term cure. For atrial fibrillation it is often highly effective.
Is catheter ablation major surgery?
No. It is a minimally invasive, catheter-based procedure, the chest is not opened.
