Radiofrequency ablation / RF

Catheter ablation is a minimally invasive X–ray surgical procedure for the treatment of tachycardia and arrhythmias using an endovascular catheter. At the same time, radio frequency current or cold is used to destroy the arrhythmogenic substrate.

In our practice, we more often use the method of radiofrequency ablation (RF), which is based on the point effect of the electrode on a site with impaired conductivity, or a source of pathological pulsation.

Radiofrequency ablation of the heart refers to low-risk operations that effectively restore the ordered rhythm of the heart. The success of the heart RF technique in various clinical forms of arrhythmias is close to 100%. The main purpose of heart RF is the point destruction (ablation) of the foci of the heart, generating pathological signals, using a radio frequency pulse. Radiofrequency ablation of the heart is a minimally invasive alternative to drug and surgical treatment of life-threatening arrhythmias.

Radiofrequency ablation of the heart is performed in a specialized cardiac surgical hospital “OKB No. 1”, equipped with an X-ray operating room and the necessary equipment for monitoring cardiac activity.


– easy portability

– fast recovery

– in most cases, there is no need for subsequent antiarrhythmic and anticoagulant therapy.

Medical City employs highly qualified specialists with international practice who can be trusted with their health.


RFA of the heart is performed with life-threatening rhythm disturbances that are not corrected with the help of medications.

With the ineffectiveness of drug antiarrhythmic treatment, the presence of pronounced symptoms associated with arrhythmia, and the risk of decompensatory heart failure.

This method is indicated for the treatment of various supraventricular paroxysmal tachyarrhythmias – AV nodular, orthodromic and antidromic forms of WPW syndrome, hidden atrioventricular junctions; moreover, the efficiency of RF reaches 98%.

Heart RF is required for patients with persistent ventricular arrhythmias that are not amenable to drug therapy, or patients with life-threatening ventricular arrhythmias that often recur after implantation of a cardioverter defibrillator.


– Consultation with a cardiac arrhythmologist or cardiologist-arrhythmologist

– ECG, daily ECG monitoring, echocardiography

– Transesophageal electrocardiostimulation

– Multispiral computed tomography of the pulmonary arteries

– Transesophageal echocardiography.

– In case of coronary heart disease or heart defects, coronary angiography, ventriculology or MRI of the heart may additionally be required

– To reduce the risk of complications, esophagogastroduodenoscopy (EGDS) is performed before surgical treatment.
