Definition: Abnormally rapid heartbeats caused by reentry of atrial impulse into the dual (fast and slow) pathways of ATRIOVENTRICULAR NODE. The common type involves a blocked atrial impulse in the slow pathway which reenters the fast pathway in a retrograde direction and simultaneously conducts to the atria and the ventricles leading to rapid HEART RATE of 150-250 beats per minute.
DF: AVNRT
Other names Tachycardia, AV Nodal Reentrant; Atrioventricular Nodal Reentry Tachycardia; Atrioventricular Nodal Reentrant Tachycardia; AV Nodal Reentrant Tachycardia
