An operationally ready national serviceman (NSman) collapsed after completing a 2.4km run at Selarang Camp in Changi on Monday.
Corporal (NS) Gan Theng Kiong, 34, suffered a cardiac arrest after finishing the run for his Individual Physical Proficiency Test (IPPT) at 9.15am, said the Defence Ministry (Mindef) in a statement yesterday. The NSman had no known prior medical condition, added the statement.
A medic attended to Mr Gan and had him transferred within a minute to Selarang Camp Medical Centre, where cardiopulmonary resuscitation was performed on him.
He was later taken to Changi General Hospital, during which efforts to revive him continued.
He was reported to have undergone an "emergency procedure" when he arrived at the hospital shortly before 10am, though Mindef did not specify what this was.
Mr Gan is currently in the intensive care unit, and is being closely monitored by specialists.
Mindef said that the Singapore Armed Forces is providing assistance to his family.
Mr Gan is the second NSman this year to have suffered a cardiac arrest and collapse after an IPPT-related activity.
In other incidents this year, an army regular died in a training area and a Mindef defence executive assistant died of cardiac arrest in detention barracks.
