The atrioventricular node (AVN) has mystified generations of investigators over the last century and continues today to be at the epicenter of debates among anatomists, experimentalists ...

A decrease in blood flow to the AV nodal artery (a branch of the RCA) can result in AV nodal ischemia and AV conduction abnormalities such as the second-degree type II AV block seen in the ECG.

The AV nodal branch was selected with a 0.014-inch guide wire, over which a 2.7 F infusion catheter was inserted into the AV nodal artery. The following solutions were infused through the catheter ...

Background: Cryoablation (CRYO) is an alternative to radiofrequency (RF) ablation in the treatment of atrioventricular nodal reentrant tachycardia (AVNRT). This study aims to evaluate the ...

This results in rapid conduction of action potentials through the atrioventricular node, causing elevated ventricular ... right or left bundle branch blocks). Causes of atrial tachycardia include ...
