Sky Sports News has been told that the all-clear was given to the player after two scans.
Last week, the club said they had been in touch with the man and were confident that his condition was not serious.
"He's in London and now he's going through some examinations because we haven't had any clarity from the Gabon national team about the reasons why he came back," Arteta said.
It's our duty to make sure that he's in good health. The player has never had that issue with everything we've done with him.
Following bouts of Covid-19, the Gabon team-mates Mario Lemina and Axel Meye were shown to have cardiovascular problems.
He's a key player for the club, although he's going through a tough period at the moment.
We have to report to the clubs. We have to be reasonable when a player's health is affected because they are paid by the club.
Arteta's side have not played since the club's 2-1 defeat toEverton in the premier league on December 6.
He has scored four league goals this season.
