AV Nodal Reentrant Tachycardia

Atrioventricular (AV) nodal reentrant tachycardia, or AVNRT, is a condition in which the heart’s rhythm is too fast. It is one of several types of tachycardia (fast rhythm) of the heart. It also is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of heart muscle cells that help control the heart’s rhythm. AVNRT is the most common type of supraventricular tachycardia, and it is more common in women than men (approximately 75% of cases occur in females). The main symptom is heart palpitations, which is a sensation that feels like the heart is beating too hard, fluttering, or skipping a beat. Treatments vary but include medication or, in some cases, electric shocks designed to restore a normal heart rhythm (a treatment called cardioversion). Frequent AVNRT attacks may require a treatment called radiofrequency ablation, in which the tissue in the heart that is causing the fast rhythm is destroyed.
