Background Atrioventricular nodal reentry tachycardia AVNRT is the most common paroxysmal supraventricular tachycardia. The relatively ineffective antiarrhythmic drugs and the predominant young age makes the catheter ablation the therapy of choice in many patients. This results in predominance of this arrhythmia in electrophysiological labs.
The aim of the study was to analyze the gender-related differences among patients undergoing the radiofrequency catheter ablation of slow pathway entrance to the atrioventricular node. Material and methods The study group comprised of consecutive patients with diagnosed atrioventricular nodal reentry tachycardia, who underwent the radiofrequency catheter ablation RFCA of slow pathway. Patients have been divided into 2 groups, based on sex. Results The overall Women were significantly younger than men AVNRT is up to 4 times more likely to affect women than men and tends to appear in young patients mean age of 32 years [].
Due to the relatively ineffective antiarrhythmic pharmacotherapy and the predominant young age of the patients, catheter ablation continues to be considered the treatment of choice [6].
This method was introduced in by Gallagher et al [7]. The recommended invasive treatment resulted in AVNRT being one of the dominant clinical entities treated in electrophysiology labs and could influence the change in the patient population. The prevalence of this arrhythmia also contributed to better training of the physicians performing the ablation procedures.
The aim of the study was to analyze the gender- -related differences among patients undergoing the radiofrequency catheter ablation RFCA of slow pathway entrance to the atrioventricular node. The study group comprised of consecutive patients with diagnosed atrioventricular nodal reentry tachycardia, who underwent the RFCA of slow pathway between January and December Standard RFCA was performed using one diagnostic decapolar deflectable catheter located in the coronary sinus.
