Three heats were held. The heat in which a swimmer competed did not formally matter for advancement, as the swimmers with the top sixteen times from the entire field qualified for the semifinals. Two semifinal heats of eight swimmers each were held. The swimmers with the eight fastest times again advanced to the finals; there, they all competed in a single final heat to earn final placements.

Nations with three or more swimmers meeting the standard could enter only three such swimmers in the final.
