About the disease

Arrhythmia is a heart disease that manifests itself as a violation of the rhythm and heart rate.

Atrial fibrillation (flickering) is the most common type of arrhythmia in clinical practice, accounting for approximately 1/3 of hospitalizations for heart rhythm disorders. Flickering is characterized by frequent and erratic, sometimes up to 350-700 per minute, contraction of individual groups of atrial muscles.

Atrial flutter is one of the most common heart rhythm disorders, accounting for about 10% of all paroxysmal supraventricular tachyarrhythmias. Atrial flutter is characterized by a regular atrial rhythm with a frequency of 250-350 beats / min.


In many cases, patients do not feel any painful conditions and the disease is detected completely by accident. However, the main complaints are palpitations, shortness of breath, and weakness. Moreover, all these manifestations usually accompany patients during the next attack, after which they gradually recede. Less common are fainting and angina, as well as frequent urination.


– Electrocardiogram (ECG),

– Load tests,

– Heart ultrasound (EchoCG).


Electrical cardioversionis a method of treating arrhythmias, which is based on stopping the circulation of excitation in the myocardium by applying an electric discharge to a certain phase of the cardiac cycle. Cardioversion requires synchronization – the application of a pulse at the time of registration of the R-wave.

Despite the fact that implantation of an electrocardiostimulator , in fact, is an operation on the heart and large vessels, it is considered a minimally invasive surgical intervention. This is not open heart surgery. The surgeon needs a small and shallow incision up to 5 cm long, which is usually made under the clavicle. Local anesthesia is most often used during EX implantation. Usually 24 hours after the procedure, you can leave the clinic and return home.

Radiofrequency ablation (RFA) is performed using a thin flexible caterer-a conductor that is inserted through a blood vessel and brought to the source of the abnormal rhythm in the heart that causes arrhythmia- < strong>arrhythmogenic zone< / strong>. Next, a radio frequency pulse is fed through this conductor, which destroys the area of tissue responsible for the wrong rhythm.

Atrial fibrillation cryoablation. A distinctive feature of this procedure is that instead of a point catheter, as in RFA, a balloon catheter is inserted into the heart, inside which nitrous oxide is fed, cooling the tissue to -80 °C. Thus is the cryoablation of tissues of the heart. This method of ablation has proven to be a faster and safer method of treating atrial fibrillation.
