Alabama Gov. Robert Bentley has been taken the hospital because of an abnormal heartbeat.
The governor's office, in a statement, said the 74-year-old governor on Wednesday morning underwent a routine procedure.
Bentley spokeswoman Yasamie August said there are no serious concerns and he is expected to return to work quickly.
The governor appeared fine Tuesday night when attending a legislative reception hosted by the state's seafood industry.
The second-term governor has faced a push from some lawmakers to impeach him in the wake of a scandal involving his relationship with a former aide. His office is also in negotiations with legislators over a large prison construction proposal.
