[Cardiac resynchronization therapy in patients with permanent atrial fibrillation].

Unlabelled: In our study we compared effect of cardiac resynchronization therapy (CRT) in chronic heart failure (CHF) patients with permanent atrial fibrillation (AF) and patients with sinus rhythm. Special feature of our work was that patients with permanent atrial fibrillation didnt have obligatory ablation of atrio-ventricular node but underwent aggressive rate control to achieve more than 90% of biventricular (BV) complexes. We used 24 hours Holter monitoring because there are data that this method is more accurate than CRT counters.

Chronic heart failure (CHF) - a widely spread manifestation of various forms of heart diseases - is characterized by high mortality. Prognosis is especially unfavorable in patients with wide QRS complex. Method of resynchronizing therapy was elaborated for the treatment of this group of patients in addition of medical therapy.

Intracardiac electrophysiological effects and antiarrhythmic activity of novel domestic class III antiarrhythmogenic drug niferidil has been studied in a group of 25 patients with paroxismal supraventricular tachycardia (PSVT) diagnosis. The drug was administered in a dose of 20 mg/kg (i.v.

[Antitachycardia and resynchronization devices in the treatment of heart failure and prevention of sudden death].

According to the modern ideas of the heart failure pathogenesis the noticeable contribution introduces ventricular dissynchrony which essence consists of the electrical and mechanical dissociation of different segments of the myocardium. In recent years the new method of cardiac resynchronization therapy has been worked out and achived good results. Its main purpose is the resynchronization of the heart by three-chamber or biventricular stimulation, which leads to an improvement of the effectiveness of heart activity.
