With aging there are changes in the cardiovascular system, which result in alterations in cardiovascular physiology ... atrioventricular conduction defects, and aortic valve calcification ...

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 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.

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