BRADDOCK, Pa. — Pennsylvania Lt. Gov. John Fetterman, the leading contender in Tuesday’s Democratic primary for U.S. Senate, is getting a pacemaker following last week’s stroke.

       His campaign said Tuesday that Fetterman was “about to undergo a standard procedure” to get a pacemaker with a defibrillator. Campaign officials say the pacemaker will “protect his heart and address the underlying cause of his stroke.”

       Fetterman has said his stroke was caused by atrial fibrillation, a type of irregular heartbeat that’s potentially serious but treatable.

       The stroke put him in the hospital in the campaign’s closing days. The 52-year-old says he’s expected to make a full recovery.

       Fetterman is facing three other candidates in the race for the Democratic nomination for Pennsylvania’s open Senate seat. Republican Sen. Pat Toomey is retiring.
