Except I have not read any Russian corroborations of poisoning and this is not the Dr. who treated Nevalny in emergency. The reuters article I quoted was from the toxicologist and you can see a lot of subtle spin even in that article. Atropine is not just used for Novichok it is used for a lot of situations, you can check. If it was Novichok they suspected (and there is no way to know this instantly or very quickly) then the way Atropine would have been used is VERY different and in massive doses. This guy MAY have treated Nevalny only after he was stabailized by emergency.

Russian doctor who treated Navalny after poisoning has died
The deputy chief physician of the Russian hospital where opposition leader Alexey Navalny was treated immediately after his poisoning "suddenly" died, according to a statement published by the hospital on Thursday.

Leonid Volkov, Navalny's chief of staff, confirmed Maximishin was in charge of treating the opposition leader. "Sergey Maximishin was the head of department that treated Alexey Navalny and was in charge of his treatment — specifically his medically induced coma," Volkov told CNN.
"(Maximishim) knew more than anyone else about Alexey's condition so I can't dismiss possibility of foul play," he added.
It wasn't the emergency ward doctor. It was the supervising doctor of the team that assessed him and put him into a coma. So this argument gets you nowhere.
