DETROIT (WXYZ) - Outgoing U.S. Rep. John Dingell underwent a procedure to correct an abnormal heart rhythm Thursday morning.
What was called a "minimally invasive procedure" was performed at Henry Ford Hospital in Detroit.
The Congressman's office released a statement just after 12:30 p.m. saying the procedure had been completed and Dingell was "resting comfortably."
"He plans to leave the hospital tomorrow and will have a light workload during the upcoming district work period. He plans to return to work as Congress reconvenes on the 24th," his office said.
According to an earlier statement, Dingell recently developed atrial fibrillation, and the procedure will seek to find the source and correct it.
The 87-year-old Dearborn Democrat is expected to stay in the hospital overnight and should be released Friday.
Spokesman Christopher Schuler says this was not an emergency procedure.
Dingell announced last month that he will not run for re-election this year. He owns the longest congressional career in U.S. history.
Dingell's wife, Debbie, is running for his Detroit-area seat.
