Fast pathway ablation in a patient with PR prolongation

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. See more 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. … See more The fundamental mechanism of AVNRT is a presence of a dual atrioventricular node physiology (present in half of the population), which acts as a re-entrant circuit within the atrioventricular node. This can take several forms. "Typical", "common", or "slow … See more Treatments for AVNRT aim to terminate episodes of tachycardia, and to prevent further episodes from occurring in the future. These … See more The main symptom of AVNRT is the sudden development of rapid regular palpitations. These palpitations may be associated with a fluttering sensation in the neck, caused by near-simultaneous contraction of the atria and ventricles against a closed … See more If the symptoms are present while the person is receiving medical care (e.g., in an emergency department), an ECG may show typical … See more WebJan 25, 2024 · The slow pathway(s) approach the compact AV node from inferiorly and have a relatively longer conduction time and an ERP that typically is short when compared to the fast pathway ERP. The different EP characteristics of the fast and slow pathway(s) can be observed during EP studies as evidence of dual AV nodal physiology. makita tagliasiepi telescopico https://lemtko.com
