The legendary actress, 78, was taken to Cedars-Sinai Medical Center in Los Angeles earlier this week for symptoms caused by congestive heart failure, described as "an ongoing condition," according to a statement from her reps.
"This issue is being addressed," the statement says. "She is currently being kept in the hospital for monitoring."
Taylor underwent heart surgery in October 2009 and has a long history of medical problems.
"Her family and close friends are appreciative of the warm support and interest of her loyal fans," the statement says, "but have asked that people respect her privacy and allow her medical team the time and space to focus on restoring her back to health."
