![]() It often ranges between two and four hours on average, depending on the simpler arrhythmias. There's a whole range of different durations, depending on the specific type of arrhythmia. Using a guidance system, we can put those catheters in the right place to record the electrical activity of the heart, sometimes to diagnose where the heart rhythm problem is coming from and to treat it (do the ablation), by either burning or freezing little bits of heart muscle to get rid of the short-circuit. The common bit to these procedures is that patients will have little punctures or holes in the leg, where we access the big vein in the leg and pass thin and long spaghetti-shaped tubes called catheters, right up into the heart. There are different forms of catheter ablation, depending on the specific arrhythmia. What is involved in the procedure and how long does it take? Are you awake? ![]() ![]() Many of the problems that cause arrhythmias can be fixed with a catheter ablation procedure. It can be done for a number of different conditions, for example atrial fibrillation, supraventricular tachycardia (SVT), atrial flutter and accessory pathways. The reason why we perform catheter ablation is because patients often have heart rhythm problems that may be fixed if we burn away, freeze away or destroy small bits of heart muscle, to treat the electrical short-circuiting in that patient's heart. The word ablation describes the controlled and localised destruction of heart muscle. Essentially, the word catheter describes the thin and long tube that is inserted into the heart through a small vein in the leg. What is a catheter ablation and what does it do?Ĭatheter ablation is a common procedure performed for patients with heart rhythm disturbances. Dr Fu Siong Ng, highly esteemed consultant cardiologist, explains what a catheter ablation does, what is the recovery like after the procedure and how many times a catheter ablation can be performed for the same patient. Catheter ablation is a minimally invasive surgical procedure that aims to correct short-circuiting in the electrical circuit of the heart.
