"He is currently in normal sinus rhythm," Nill said in a release issued Wednesday. "He was released from the Cleveland Clinic today and is expected to return to Dallas tomorrow. He will be monitored closely and may require further treatment."
Peverley collapsed on the team's bench during a game against the Columbus Blue Jackets on March 10. The procedure performed on Tuesday was to fix an irregular heartbeat that was diagnosed in training camp.
The 31-year-old from Kingston, Ont., decided not to have the procedure after that diagnosis. He chose a less invasive adjustment and medication.
Peverley missed the week before his collapse when he didn't feel well.
As for his return to the NHL, Peverley has been ruled out for the season, but there was no word yet on his plans for the future.
"There is no decision being made at this time on his ability to return to hockey participation,” Nill said.
The game between the Stars and Blue Jackets that was postponed after Peverley went into medical distress has been rescheduled for April 9.
