Khedira underwent an "electrophysiological study and successful interventional therapy", the Italian champions said in a statement on their website.
"After a short period of convalescence (he) will be able to resume his activity approximately within one month."
Khedira has played only 15 times in all competitions for runaway Serie A leaders Juve this season due to injuries.
