Premature cardiac beats can be eradicated with radiofrequency ablation treatment. Premature cardiac beats, also known as premature beats and preterm contractions, are heart beats that occur prematurely by issuing impulses from an ectopic pacing point on top of a regular heart rhythm. Radiofrequency ablation is an effective treatment for premature beats. It is an interventional technique in which an electrode catheter is delivered to a specific part of the heart chambers through a vein or an artery, and radiofrequency current is released to cause coagulative necrosis of the endocardium and subendocardial myocardium causing the cardiac lesion, thus interrupting the abnormal conduction pathway and the point of origin of the tachyarrhythmia. Radiofrequency ablation can treat premature heartbeats at their root cause, because the endocardium and subendocardial myocardium of the cardiac lesion are already coagulatively necrotic, and there will be no more blockage of abnormal conduction, thus curing premature heartbeats at their root cause. If diagnosed with premature heart beat, it is recommended to carry out standardized treatment as early as possible, and radiofrequency ablation can be selected according to the specific conditions of the patient to treat the disease fundamentally, in order to reduce the adverse effects of the disease.
