SAMSUNG Electronics chairman Lee Kun-hee has been hospitalised after suffering a heart attack.
The 72-year-old chairman of the world's biggest smartphone maker had trouble breathing on Saturday and was sent to an emergency room. He was found to be suffering cardiac arrest and hospital staff performed CPR. He is currently undergoing treatment at Samsung Medical Centre.
According to the hospital, his heart condition has improved and he is in recovery.
Samsung Electronics is the flagship of the Samsung Group, South Korea's largest conglomerate of companies.
After Lee took over the group from his father in 1987, he played an instrumental part in building the electronics arm up into a global company which now sells the whole range of electronic products from semiconductor components to appliances.
Samsung is run by three co-chief executives, but insiders say Lee makes the final decisions when it comes to key strategies affecting the company.
Analysts say Lee's health problems come during a time when Samsung Electronics is experiencing slow growth in its mobile unit. In Q1 2014, the mobile business of Samsung Electronics declined in operating profit for the first time in more than three years. The company on the whole is looking for a new growth market beyond its mobile and chip businesses.
