Search for: [Abstract = "Atrioventricular nodal reentrant tachycardia \(AVNRT\) is the most common type of tachycardia with a narrow QRS complex. RF ablation of slow\-pathway ablation is effective and safe procedure. Apart from patients who objectively captured a recurrence of AVNRT, nearly 30% still report different types of palpitations and the origin of these symptoms is not completely elucidated. The aim of the study was demonstration of electrophysiological and clinical parameters associated with a higher risk of AVNRT recurrence and \/ or subjectively experienced heart palpitations after successful RF ablation \(define the most probable etiology\). In the present study it has been proven that ablation of slow pathway is an effective and safe method of treatment for AVNRT and the risk factors for higher recurrence rates of tachycardia are\: female, atypical forms of AVNRT, a shorter cycle length of arrhythmia , slow pathway modification, and low power value achieved during RF application. Among patients without documented arrhythmia recurrence the most common cause of subjective symptoms were\: atrial arrhythmias, symptomatic episodes of sinus tachycardia, and ventricular arrhythmia. Factors favoring the appearance of those abnormalities also has been demonstrated."]
