The atrioventricular node (AV Node) is a bundle of conduction cells that regulate the communication of atrial electrical activity with ventricular electrical activity. The AV node has a long ...

Having an accelerated junctional rhythm occurs when the atrioventricular node in your heart beats too quickly. It happens as a result of damage to your heart’s primary natural pacemaker. There’s no ...

Atrioventricular reentrant tachycardia (AVRT) is a rhythm problem in your heart that makes it beat too fast. It results from an extra connection between your upper and lower chambers. You might hear ...

Mobitz type I, also known as the Wenckebach block, is a subtype of second-degree atrioventricular (AV) block. Mobitz type I is a type of conduction disorder, which happens when the electrical signals ...

Atrioventricular (AV) nodal reentrant tachycardia (AVNRT) is an irregular heart rhythm that can cause excessively fast heart rates. Though not usually serious, early diagnosis can help prevent severe ...

When high doses of AV blocking drugs are not successful to lower ventricular rates in the setting of atrial fibrillation, AV node ablation can be utilized. Remember that all atrial action potentials ...

Many studies have demonstrated that macrophages have multiple functions in different organs and tissues beyond their classical phagocytic activity. However, the specific functions of heart-resident ...
