Shane continues to cling to life at Hoag hospital in Newport Beach, CA. After arriving at the emergency room in full cardiac arrest on Tuesday morning he was resuscitated to stable rhythm and blood pressure, but has not regained consciousness.

Tragically, it strikes healthy young people and often is the first and only presentation of a heart problem.
