In a nervous, restless, or excited manner showing agitation.
From 'agitated' (adjective, from Latin agitatus) plus the adverbial suffix '-ly'. The root agitare originally meant 'to drive cattle' before evolving to mean 'to disturb emotionally' around the 16th century.
The way adverbs like 'agitatedly' evolved shows how English loves to add '-ly' to almost any adjective—but some of the most expressive adverbs come from participles of verbs, creating a direct line from action to manner of doing it.
