*Alphas Leken Kishoyian had originally finished in 48.39, the last in his heat, but, since the starter's gun had fired before he settled in his blocks, a rerun was ordered in which he had to run by himself faster than 46.49, the time of the last fastest loser. He succeeded and was given the place in the final.^[4]
