The new ACC and AHA criteria for cardiac devices emphasize more risk stratification, reflecting advances in the field in ...

New research highlights postnatal regeneration limits and pathological remodeling of the cardiac conduction system after myocardial infarction, uncovering mechanisms behind clinical ...

The impulse is then passed to another node within the heart – the atrioventricular node (AVN). This node is in the lower part of the right atrium.

However, this short-term regulation did not explain why the heart conduction system generally slowed down at night. “All the arrows pointed to the fact that there might be an intrinsic rhythm with the ...

The normal cardiac conduction system delivers the electrical impulse to both the right and left ventricles simultaneously; however, in the presence of a left bundle branch block or right bundle ...

while the other half are idiopathic or due to fibrosis of the cardiac conduction system which occurs during the aging process. QRS duration of > 120 ms. Absence of Q wave in leads I, V5 and V6.
