The failing health of Lee Kun-hee, the chairman of Samsung Electronics, has yet again emerged as a massive concern to the management of the sprawling Samsung Group.
Lee underwent an emergency medical procedure at the Samsung Medical Center on Sunday after suffering cardiac arrest.
Hospital officials say the 72-year-old is stable and showing signs of improvement.
"The chairman showed symptoms of heart failure and underwent an emergency procedure, which involved a stent placement. He's now in a stable condition and recovering."
Samsung's top executives, including officials from the group's Corporate Strategy Office visited the hospital, and held meetings to discuss the next steps.
Experts speculate Samsung will not take any immediate action, but they'll keep a close eye on the situation for the time being.
In 2008, when Lee gave up his position as Samsung Group chairman after a special inquiry which found him guilty of tax evasion and breach of duty, the group implemented several management reforms, but did not enter an emergency business management mode.
Lee returned to the frontlines of management in March 2010.
The chairman has a history of respiratory problems dating back to the late 1990s when he had surgery for lung cancer.
He was also hospitalized last summer with symptoms of light pneumonia.
With Lee's health problems taking a turn for the worst, Samsung is also expected to accelerate its corporate succession to Lee's three children.
Lee's only son -- Samsung Electronics Vice Chairman Lee Jay-yong, will likely succeed him eventually.
