In brief: Possibly

It is often hard to be certain what causes fast heart beating.
If you drink soda with a lot of sugar, it could be the caffeine and not the sugar for instance. Sometimes in early diabetes the blood sugar actually drops after eating sugar and a low blood sugar can definitely cause tachycardia. There may also be other yet unknown mechanisms for how sugar might cause fast heart beating.
