In this EKG tutorial it says
Depolarization conducts slowly through the AV node, since it is carried by slow moving $\ce{Ca++}$ ions...
Is there a difference between $\ce{Ca++}$ and $\ce{Ca}^{2+}$?

Is there a difference between $\ce{Ca++}$ and $\ce{Ca}^{2+}$?
The answer to this question is: No. There is no difference between the two, they are merely two different notations.
They are the same.
The IUPAC Green Book writes:
$\ce{Al^{3+}}$ is commonly used in chemistry and recommended by [74]. The forms $\ce{Al^{+3}}$ and $\ce{S^{-2}}$, although widely used, are obsolete [74], as well as the old notation $\ce{Al^{+++}}$, $\ce{S^=}$, and $\ce{S^{--}}$.
