Hosni Mubarak lies on a hospital bed inside a cage of mesh and iron bars in a Cairo courtroom as his trial began on charges of corruption and ordering the killing of protesters during the uprising that ousted him. He would eventually be sentenced to life in prison.
Cairo, Egypt (CNN) -- Former Egyptian President Hosni Mubarak, 84, was declared clinically dead shortly after arriving at a military hospital in Cairo, where he was taken after suffering a stroke and cardiac arrest, medical sources told the state-run Mena News Agency.
Official reports of the stroke and cardiac arrest came earlier Tuesday. Adel Saeed, spokesman of the Egyptian prosecutor, had told CNN that Mubarak's heart had stopped, and that personnel revived him with "electric shocks and CPR." State-run Nile TV reported that Mubarak suffered a stroke.
Elizabeth Cohen, CNN's senior medical correspondent, said that "clinically dead" usually refers to someone who is brain-dead. In such a case, an electroencephalogram would indicate no real brain activity, she said.
Meanwhile a member of Egypt's ruling military council has disputed Mena's report.
"He is not clinically dead as reported, but his health is deteriorating and he is in critical condition," Gen. Mamdouh Shahin, a member of the Supreme Council of the Armed Forces, told CNN.
Shahin did say that Mubarak's heart had stopped, but he "was saved by electric shocks (and) then placed on respirator." Mubarak then suffered a brain clot, Shahin said.
Mubarak was sentenced to life in prison June 2 for the killing of pro-democracy demonstrators last year. He already was suffering from health problems and attended court on a gurney.
His health has been reported to be in decline since he was ousted as president of Egypt in February 2011. On June 11, a prosecutor's spokesman said Mubarak's health deteriorated after the verdict, and that defibrillators had been used several times to revive him "due to heart complications."
Mubarak's latest health crisis came on a day when both candidates who participated in a presidential runoff claimed victory.
