Radiofrequency ablation (RFA) is a medical procedure used to treat certain types of cardiac arrhythmias, which are abnormal heart rhythms. It is a minimally invasive technique that involves the use of heat generated by radiofrequency energy to selectively destroy or modify specific areas of heart tissue responsible for causing the arrhythmia.

How is radiofrequency ablation performed?
During the procedure, thin, flexible catheters are inserted through a blood vessel (typically in the groin) and guided to the heart. The catheter has a special tip with an electrode that delivers controlled radiofrequency energy to the targeted heart tissue. The energy creates heat, which destroys the tissue responsible for the arrhythmia. The procedure is guided by real-time imaging techniques such as fluoroscopy or three-dimensional mapping systems.
Is radiofrequency ablation painful?
Patients are usually given local anesthesia and conscious sedation or general anesthesia to ensure comfort during the procedure. While the ablation itself is typically not painful, some patients may experience mild discomfort or a sensation of pressure when the catheter is positioned in the heart.
