The Oscar-winning actor Kevin Spacey, 64, underwent an MRI scan after the scare during the 15th Tashkent International Film Festival in Uzbekistan, The Sun writes.
He became unwell while touring the Afrasiyab Museum in the ancient Silk Road city of Samarkand - and felt his "entire left arm go numb for about eight seconds".
House of Cards star Spacey was taken to the Innova Diagnostic Clinic in the city to undergo a series of tests - including an MRI scan. It was feared the actor could have suffered a heart attack, but doctors later gave him the all-clear.
A source close to the actor said: “Mr Spacey was taken to a medical centre over health concerns."He was treated professionally by doctors and staff and found to have no problem with his heart.”
The Superman Returns star appeared on stage at the festival later that night, and told the crowd his health was "normal". Spacey said: "It made me really take a moment and think about how fragile life is - for all of us."
