AV Nodal Reentrant Tachycardia (AVNRT) is a type of tachycardia (fast rhythm) of the heart. It is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of His. AV nodal reentrant tachycardia is the most common regular supraventricular tachycardia. It is more common in women that men (approximately 75% of cases occurring in females). The main symptom is palpitations. Treatment may be with specific physical maneuvers, medication, or rarely DC cardio version. Frequent attacks may require radiofrequency ablation, in which the abnormally conducting tissue in the heart is destroyed.
