According to the statement released by the Red Wings, Fischer was resting at home on Monday evening when he experienced the abnormal rhythm and he returned to Detroit Medical Center for further testing and observation.
Fischer was released Wednesday and is scheduled to have more tests at the University of Michigan Medical Center. The statement did not specify when Fischer would have those tests.
"The Red Wings and Jiri appreciate the media and public's continued respect for the Fischer family's privacy during this time," the statement read.
The news comes over a week after Fischer collapsed on the bench in convulsions during a game against the Nashville Predators on Nov. 21.
Fischer was stricken in the first period. Team physician Tony Colucci wasn't able to detect a pulse after Fischer collapsed, and an auto defibrillator was used on the 25-year-old player.
After performing CPR, Colucci said he detected a good pulse and
Fischer was taken from the arena by ambulance to Detroit Receiving
Hospital. Colucci said Fischer's heart might have stopped, but he
didn't know for how long.
The team announced to the crowd that Fischer had a
seizure, but Red Wings coach Mike Babcock later said Fischer's
heart had stopped.
The day after the incident, Colucci said the defibrillator indicated that
Fischer's heart may have been experiencing ventricular tachycardia,
a kind of racing heartbeat, or ventricular fibrillation, a heart
fluttering. Both can cause death, and ventricular fibrillation is a
common cause of sudden cardiac arrest.
Fischer was diagnosed with a heart abnormality in 2002, causing
him to miss two days of practice.
Colucci said tests were being done to determine whether the
convulsions were related to the abnormality. When the 2002 result
came back, Fischer was given a stress test that he passed, and he
said his heart essentially is a little thicker than normal.
He was placed on injured reserve and the team recalled
defenseman Kyle Quincey from Grand Rapids of the AHL.
