The indications for radiofrequency ablation are tachycardia, arrhythmia, such as a rapid heartbeat, which is conveyed with precision in a variety of ways, that is, an extra wire, or in some cases there are many loops inside the heart that cause tachycardia or a chaotic heart rate. There is also a condition where there is a focal lesion which causes premature beats in the heart. All these cases can be solved by radiofrequency ablation technique. Radiofrequency ablation is a technique that delivers an electrical body to the ventricle through a minimally invasive local puncture, releasing a powerless radiofrequency current. It is localized myocardial edema and necrosis, and through this change to solve the problem of bypass conduction or foldback loop, or localized focal problems, eliminating the arrhythmia, called radiofrequency ablation.
