Accounting for approximately 70% of supraventricular tachycardias (SVT), atrioventricular nodal reentrant tachycardia (AVNRT) is the most common SVT in adults. Catheter ablation of the AV nodal slow pathway, usually localized anterior to the lower portion CS os, as a treatment strategy for AVNRT ...

Lower panel, Intracardiac recordings during ablation of the slow pathway. Note the sharp (blue arrow, left lower panel) and broad (red arrow, right lower panel) potentials recorded between the atrial and ventricular electrograms at the ablation sites. Those potentials were suggested to reflect activ...

She was referred for electrophysiology (EP) study and ablation of her SVT. EP catheters were placed in the morphologic right atrium and right ventricle, the coronary sinus, and the His position. Of note, the His bundle electrogram was recorded in the posterior septum of the morphologic right...
AV blocking agents such as beta-blockers and non-dihydropyridine calcium channel blockers (diltiazem or verapamil) can help to decrease the frequency of episodes. The usual approach to the treatment of AVNRT is medical therapy with AV blocking agents and referral for ablation if...
