A procedure intended to eliminate or modify a focus or re-entry circuit that causes an arrhythmia in the heart. (ACC)

(catheter ablation) Catheter ablation is an invasive procedure used to remove or terminate a faulty electrical pathway from sections of the hearts of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter, SVT and Wolff-Parkinson-White syndrome.

(catheter ablation) Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter. Energy sources are commonly direct current (DC-shock) or alternating current at radiofrequencies (usually 750 kHz). The technique is used most often to ablate the AV junction and/or accessory pathways in order to interrupt AV conduction and produce AV block in the treatment of various tachyarrhythmias.

Radiofrequency (RF) catheter ablation (RFCA) has revolutionized treatment for tachyarrhythmias and has become first-line therapy for some tachycardias. Although developed in the 1980s and widely applied in the 1990s, formalized guidelines for its use in clinical practice were not developed until some years later.

Cardiac ablation is a procedure that can correct heart rhythm problems (arrhythmias). Cardiac ablation works by scarring or destroying tissue in your heart that triggers or sustains an abnormal heart rhythm.
