Comedian Lucille Ball was released from Cedars-Sinai Medical Center after nearly a week's stay, a spokesman said in Los Angeles.

"She's doing fine," said hospital spokesman Ron Wise, after the 76-year-old Ball was released Sunday afternoon.Ball was brought in Wednesday by her husband, Gary Morton, after complaining that she did not feel well, Wise said.

"There was initial concern that she was having cardiac problems, but subsequent tests indicated that her general condition was good," Wise said.

He did not know if doctors had determined the problem, but "if it was anything significant, she wouldn't have been out this fast," Wise said.
