Paroxysmal atrioventricular nodal reentrant tachycardias: epidemiology, clinical picture, diagnostics, treatment (review)

Abstract

Nowadays paroxysmal AV nodal reentrant tachycardia (AVNRT) is one of the most widespread arrhythmias. In most cases AVRNT is a recurrent process, and it worsens the life quality of such patients, reduces their workability and increases the incidence of applying for medical help. Thus AVNRT today is of special attention among investigators. The interest of clinicians to the problem of cardiac arrhythmias is associated with permanent dissatisfaction with the results of antiarrhythmic therapy and also with the rapid development of the surgical methods of treatment, i.e. the use of radio frequency catheter ablation.
