BRADDOCK, Pa. (WTAJ) — Pennsylvania Lieutenant Governor John Fetterman’s campaign announced he’ll be undergoing a procedure to implant a pacemaker, just hours before the polls close for the primary election.

In a statement from Fetterman’s campaign, they said he’s about to undergo a “standard procedure to implant a pacemaker with a defibrillator.” This comes four days after Fetterman had suffered a stroke.

The procedure should be short and will help protect his heart and address the underlying cause of his stroke, atrial fibrillation (A-fib), by regulating his heart rate and rhythm, according to the statement

Fetterman, who is a Democratic candidate for the U.S. Senate, said he was doing well. He’s currently staying at Lancaster General Hospital and will not be attending his primary election party in Pittsburgh.

Fetterman’s wife, Gisele, spotted the symptoms and got him to the hospital where they were able to spot and remove a clot that put his heart in an A-fib rhythm for too long.
