Update

More details on Jiri Fischer:

"His heart had stopped, and there was no pulse," coach Mike Babcock said. "But they hooked up the auto defibrillator, and they shocked him. The heartbeat that leads to death, they got that stopped, and going, and they continued with the CPR.
"It's our understanding that things are fine, and that he is going to be fine. He's stable."

Scary stuff. Glad to hear he's doing all right, though.
