The ventricles are not reaching systole in every cardiac cycle.

The heart is not pumping any blood at all.

The atria are not pumping blood. $\"\"$

Answer: (a) The ventricles are not reaching systole in every cardiac cycle.

Second degree heart block involves a greater level of signal slowing, to the extent where some signals don’t reach the ventricles at all.
