Radiofrequency ablation (RFA) is a medical procedure in which part of the electrical conduction system of the heart, tumor or other dysfunctional tissue is ablated using the heat generated from high frequency alternating current (in the range of 350–500 kHz). (1)
SCOPUS gave 16,247 results (July 28, 2015) for a search of radiofrequency ablation in a title.
