Olson, a Texas Republican, was treated for bradycardia — a slow heart rate — and was equipped with a pacemaker, CNN reported.
“While working out in the House gym, I got quite dizzy and fainted,” Olson said in a press release, according to CNN. “After being rushed to George Washington University Hospital, it was determined that I had a condition called bradycardia, which is medical talk for a slow heart beat. Whatever they call it, it wasn’t good and I don’t recommend it.”
The CNN report said Olson is expected to return to work next week.
