Radiofrequency Ablation Procedure for Heart Palpitations

Radiofrequency ablation is a medical procedure where a catheter is inserted through the blood vessels in the lower limbs and guided into the heart chambers. Once the target area is identified, controlled electrical energy is applied to create localized tissue damage, effectively treating various types of rapid heart arrhythmias. This procedure is considered safe and well-established, with minimal risk to the patient.

When Is RFA Recommended?

Not all cases of heart palpitations require radiofrequency ablation (RFA). This procedure is typically used for treating conditions such as atrial fibrillation, ventricular premature contractions, or other forms of tachyarrhythmias. In contrast, atrial premature beats often do not require such intervention. Patients undergoing RFA need to be hospitalized for monitoring before and after the procedure.

Preparation for the Procedure

Prior to the surgery, patients must fast for at least 8 hours due to the use of local anesthesia. Additionally, all anti-arrhythmic medications should be discontinued three days before the procedure, as residual substances in the body may interfere with test results and affect the accuracy of the treatment.

What Happens During the Procedure?

The process begins with sterilizing the insertion site, followed by local anesthesia. Once the area is numb, a small incision is made to access the blood vessel. A catheter is then carefully guided to the targeted area in the heart. Once the problematic tissue is located, radiofrequency energy is delivered to eliminate the abnormal electrical pathways. Patients remain conscious throughout the procedure, allowing for real-time feedback, which contributes to a success rate exceeding 90%.
