Former Philippine President Ferdinand Marcos was hospitalized Friday after suffering what apparently was congestive heart failure, spokesmen said.

Marcos, 71, was taken by ambulance to St. Francis Hospital. He was admitted upon the recommendation of his physician, Calvin Wong, because of "the acute onset of congestive heart failure" Friday morning, spokesman Gemmo Trinidad said.Marcos was in guarded condition Friday afternoon and was expected to be in the hospital for a couple of days, said St. Francis Hospital spokeswoman Norma Kop.

Preliminary findings indicated Marcos had indeed suffered congestive heart failure and an arrhythmia, or irregularity in the heartbeat, she said.

Asked to comment on allegations that Marcos, who was deposed as Philippine president in 1986 and is now under indictment in the United States, had earlier faked symptoms of illness, Kop replied: "He had a heart irregularity, and that can be pretty serious."

He was resting comfortably with his wife, Imelda, nearby, and he was able to eat and was in good spirits, she said.

Marcos was given chest X-rays, an EKG and diagnostic tests, but the results would not be available until Saturday, she said.

Wong said Marcos did not have a heart attack. Congestive heart failure means the heart is unable to pump the amount of blood required by the body.

"Mrs. Marcos is very worried," Trinidad said. "She's in tears; she's always in tears."

Marcos began having chest pains around 4 a.m., after learning that his pregnant daughter, Imee Manotoc, who lives in exile in Morocco, was having medical problems and would have to deliver by Caesarian section, Trinidad said.
