The slow pathway (which is usually targeted for ablation) is located inferior and slightly posterior to the AV node, often following the anterior margin of the coronary sinus. The fast pathway is usually located just superior and posterior to the AV node. Visa mer AV-nodal reentrant tachycardia (AVNRT) is a type of abnormal fast heart rhythm. 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 … Visa mer The fundamental mechanism of AVNRT is a presence of a dual atrioventricular node physiology (present in half of the population), which … Visa mer Treatments for AVNRT aim to terminate episodes of tachycardia, and to prevent further episodes from occurring in the future.
