AV nodal reentrant tachycardia (AVNRT) or atrioventricular nodal reentrant tachycardia 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 than men (approximately 75% of cases occur in females). The main symptom is palpitations.
