They address tissue effects, cryotechnology, and clinical applications of procedures like ablation for atrioventricular nodal reentry tachycardia
(AVNRT) and atrial flutter and fibrillation, septal pathways, balloon-based and endocardial cryoablation, epicardial cryoablation for patients undergoing mitral valve surgery, and cryoablation of ventricular tachycardias, as well as history and mechanisms.
An impulse can circle in nodus atrioventricularis and cause atrioventricular nodal reentry tachycardia
. Various forms of WPW syndrome are described (exact WPW syndrome, latent ventricular preexcitation, permanent junctional reciprocating tachycardia) in a presence of aberrant atrioventricular pathways in heart.
On the basis of indication, the electrophysiology market is divided into atrial fibrillation, ventricular fibrillation, ventricular tachycardia, atrial tachycardia, atrial flutter, Wolff-Parkinson-White (WPW) syndrome, and atrioventricular nodal reentry tachycardia
