Kiss singer/guitarist Paul Stanley suffered a sudden heart ailment prior to the band's Friday show at Soboba Casino in San Jacinto, Calif., necessitating the group play without him as a trio for the first time in its 30-plus-year career.

"During sound check, my heart spontaneously jumped to 190 plus beats per minute where it stayed for over an hour necessitating paramedics to start an IV and give me a shot to momentarily stop my heart and get it into a normal pattern," Stanley said on the Kiss Web site. "Not knowing if this episode was life threatening made it even more exhausting," Stanley's present condition is unknown.

At the show, bassist Gene Simmons, guitarist Tommy Thayer and drummer Eric Singer did their best to cover for Stanley, with fans from the audience helping out with vocals on "Christine Sixteen" and Singer taking the mic for "Nothin' to Lose" and "Black Diamond."

The show was the last of three Kiss had on tap for this summer. As previously reported, the second volume of the group's "Kissology" archival series is due Aug. 14.
