Noncontact three-dimensional mapping guides catheter ablation of difficult atrioventricular nodal reentrant tachycardia

High-density mapping of the tachycardia circuit in atrioventricular nodal reentrant tachycardia

“…To our knowledge, this represents the first published report of a high-density activation map of the AVNRT circuit, without the use of a noncontact balloon 1 . This case illustrates the ability of high-density mapping to allow novel visualization of activation in tachycardia circuits, while avoiding the limitation of noncontact mapping.…”

High-density mapping of the slow pathway in a patient with atrioventricular nodal reentry given intranasal Etripamil during the NODE-1 study

“… 3 Voltage mapping of the atrial septum has also been reported to be another method of identifying the slow pathway. 3 , 4 In patients with AV node reentry, with adjustments in the voltage settings, a discrete low-voltage channel appears in the low posterior atrial septum near the CS os leading toward the compact AV node. Within the low-voltage bridge, typical slow pathway electrograms can be seen.…”

Dual atrioventricular nodal physiology in young child

“…Atrioventricular nodal reentrant tachycardia is the most common supraventricular tachycardia associated with dual atrioventricular nodal physiology [3][4][5][6]. We present a case of dual atrioventricular nodal physiology in a 12-year-old Italian boy.…”
