Nationals manager Dave Martinez will be away from the team indefinitely after undergoing what general manager Mike Rizzo called a "minor" cardiac procedure Monday.
Martinez, 54, left Sunday's game against the Braves during the sixth inning due to what was described only as an illness. Rizzo told reporters Monday in St. Louis that Martinez had experienced chest pains in the dugout during the game and underwent a cardiac catheterization Monday.

The Mayo Clinic describes a cardiac catheterization as a procedure used to "diagnose and treat certain cardiovascular conditions." Rizzo said Martinez is waiting on additional test results that will help determine what comes next.
