Cardiac

A hole in the wall of the heart separating the atria or in the wall of the heart separating the ventricles.

Impulses traveling through the heart’s upper chambers (the atria) are delayed in the area between the upper and lower chambers (the AV node) and fail to make the ventricles beat at the right moment

This is when the veins in the neck become engorged and fluid accumulates in the legs (peripheral oedema) or abdominal cavity heart are affected then a combination of the above features is seen. This is usually referred to as Congestive Cardiac Failure (CCF)
