Former International Olympic Committee (IOC) president Juan Antonio Samaranch was rushed to the hospital after he fainted at a conference in Madrid.
A statement made by Madrid's Clinico San Carlos said that the 87-year-old Samaranch had cardio-vascular problems and fell ill during a conference in Madrid on Wednesday.
"It is nothing serious," Spain's Olympic committee head Alejandro Blanco said. "Everything will be back to normal. The situation is under control."
Samaranch was head of the IOC from 1980 to 2001. Recently, he has been pushing Madrid's bid to host the Olympics in 2016.
On July 17, 2001, his 81st birthday, he was hospitalised in Lausanne, Switzerland for "extreme fatigue". He was hospitalised again in Barcelona a month later for arterial hypertension due to the effort of organising the IOC Congress in Moscow.
