Atrioventricular complete block occurring 12 years after successful ablation of slow-slow atrioventricular nodal reentrant tachycardia

Türk Kardiyoloji Derneği Arşivi, 2013
Atrioventricular nodal reentrant tachycardia (AVNRT) is the most frequent form of paroxysmal supraventricular tachycardia. Selective radiofrequency (RF) catheter ablation of the slow pathway is an ideal method for treatment of patients with AVNRT ...

[Atrioventricular nodal reentry tachycardia in children].

Tidsskrift for den Norske laegeforening : tidsskrift for praktisk medicin, ny raekke, 2006
Atrioventricular nodal reentry tachycardia is a supraventricular tachycardia with a double nodal pathway between the atria and the ventricles located in the normal AV-node. It may cause a reentry circuit. Atrioventricular nodal reentry tachycardia is one of the most common supraventricular tachycardias in adulthood, but is seldom diagnosed in children--

Dynamical mechanism of atrial fibrillation: a topological approach [PDF]

, 2017
While spiral wave breakup has been implicated in the emergence of atrial fibrillation, its role in maintaining this complex type of cardiac arrhythmia is less clear.
