DALLAS -- Play was halted during the Dallas Stars game at the American Airlines Center Monday night after Dallas center Rich Peverley collapsed on the team's bench after a "cardiac event."
At 11:30 p.m., the Stars announced the forward was listed in stable condition.
"First thing Rich asked me when I spoke to him, "How much time left in the period," said coach Lindy Ruff.
The game has been postponed by the NHL, and will be rescheduled at a later date.
"As a result of the emotional state of the players on both teams caused by the medical emergency, the game is being postponed," the league said in a statement.
Players were yelling and banging their sticks against the boards, attempting to get medical attention to the fallen player. He was rushed from the ice, and Peverley's wife, Nathalie, accompanied him in the ambulance to UT Southwestern St. Paul University Hospital.
"When he dropped, it was red alert," Ruff said. "Don't worry about the game. It was about getting the doctors."
Peverley missed the preseason and the season opener because of a procedure to correct an irregular heartbeat, a condition diagnosed during a training camp physical. He made his Stars debut on Oct. 5 against Washington.
"We monitor him closely for a different type of arrhythmia he has," Dr. Gil Salazar said after the game was called Monday. "He does have a pre-existing condition, and the condition — a normal quivering of the heart that does not allow him to send blood to places where he needs to, in his brain and heart."
Peverley sat out last week's game at Columbus because of an irregular heartbeat. He had felt strange after last Monday's game and couldn't fly.
Peverley then played in Dallas' next two games before Monday.
Dr. Salazar said Monday night Peverley was treated successfully, that he was aware of where he was, and that he wanted to get back in the game when he regained consciousness.
"We treated (Peverley) for a cardiac event successfully," said Salazar of UT Southwestern Hospitals. "We provide oxygen for him. We started an IV. We did chest compressions on him and defibrillated him, provided some electricity to bring a rhythm back to his heart, and that was successful with one attempt, which is very reassuring.
"As soon as we treated him, he regained consciousness," Salazar said. "He was able to tell me where he was."
"I thought the medical staff did an unbelievable job tonight," Ruff said after the game was postponed.
Salazar said more extensive testing will occur over the next day or so.
Peverley had played in 62 of the Stars' 64 games this season and recorded seven goals and 23 assists. He was acquired last July from Boston with forward Tyler Seguin and defenseman Ryan Button for forwards Loui Eriksson, Reilly Smith and Matt Fraser, and defenseman Joe Morrow.
The Columbus Blue Jackets led Monday night's game 1-0 when play was stopped 6:23 into the first period.
