Electrophysiologic Principles of Radiofrequency Lesion Making

Abstract

Understanding of the electrophysiologic principles of radiofrequency lesion making is necessary to ensure reliable results in surgical procedures using this technique. A radiofrequency lesion is produced by tissue electrocoagulation. Its method of formation and factors affecting heat generation and loss are discussed. Guidelines for making radiofrequency lesions, based on electrophysiologic principles are outlined.
