The 37-year-old husband of Kim Kardashian went on to perform in couple hours after leaving the hospital, reported E!Online.
"West is fine and didn't have a major health scare or seizure. He just suffered a migraine and went to the hospital simply as a precaution," a source said.
West has not tweeted about his visit to the hospital but his wife posted a photo of them from their recent date night in Melbourne.
Earlier in the week, Kardashian and West were spotted shopping in the Aussie city's central business district.
