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.

Atrioventricular nodal reentrant tachycardia (AVNRT) is a rapid, irregular heartbeat that starts suddenly and without warning and may stop just as abruptly. It is a common type of what's called ...

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 ...

This represents a greater disturbance of AV nodal conduction than first-degree AV block ... prolonged S wave upstroke and/or premature ventricular beats with a left bundle branch block (LBBB) ...

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 ...

of patients with AV block caused by drugs had blocks at the level of the AV node. In addition, infranodal block was revealed in only 14% (eight of 57) of them. Thus, one could suggest that if the ...

Atrioventricular nodal re-entrant tachycardia (AVNRT) can trigger atrial fibrillation (AF), but the incidence of AVNRT as a cause of AF is unclear. Identification of patients with AVNRT could ...
