Dr. Friedman answers the question: 'What is AV Node Reentrant Tachycardia?' — -- Question: What is AV node reentrant tachycardia, and what is the best way to treat this? Answer :AV node reentrant ...

A first-degree AV node block occurs when conduction through the AV node is slowed, thus delaying the time it takes for the action potential to travel from the SA node, through the AV node, and to the ...

The Effects of Aging on the Sinus Node and the Cardiac Conduction System Once the atria are activated, the electrical impulse travels sequentially through the AV node, His bundle, and left and right ...

The term bradycardia refers to an abnormally slow heart rate, of under 60 beats per minute (bpm). The heart has a complex system of nerves that conduct the electrical impulses fired by the sino-atrial ...

Abnormal heart rhythms (dysrhythmias) are caused by disturbances in electrical impulse generation or by abnormal conduction between chambers of the heart – principally within the sinus node, ...

In patients with atrioventricular septal defect (AVSD), the occurrence of nonsurgical AV block has been reported. We have looked for an explanation in the development of the AV conduction system.
