Chris,
When someone is having an epelictic (sp - Dsylexic) seisure, the first thing to do is to ensure they do not swallow their tounge, so they'll continue to breath. Breathing is a good thing.
An aside, in high school, we were playing Handle's Mesaiah for the winter concert (OK I was in high school so long ago that we could do sacred music) with the 100 person choir and either the band or orchestra (band for the 2:00pm and orchestra for the 5:00pm) and one of the French horn players had an epelictic seisure. An oboe player, and boy scout, knew exaclty what to do. The heat of the 200 kids required for the performance and the packed audence may have triggered the seisure, and honking away on the Mesaiah. I think I was singing that performance. I did it serveral years, once in choir, two times playing tuba in band and once on tuba in orchestra as well as once on double bass in orchestra.
