The heat was a little too many for some people at the Ed Sheeran concert Saturday at Acrisure Stadium.
Pittsburgh Public Safety says dozens of people were treated by EMS.
In total there were 37 calls for service, including 17 taken to the hospital.
Most of those were heat-related incidents but a few were due to falls, another person had a seizure and two cardiac arrests.
One person tearing down the setup inside the stadium and a paramedic from an agency outside of Pittsburgh went into cardiac arrest on Art Rooney Avenue, outside the stadium.
Two were resuscitated and transported to a local hospital.
"Again, with the quick response by numerous crews and agencies, the patient was resuscitated after receiving several shocks and was transported to AGH," Pittsburgh Public Safety said in a release.
