The electrophysiologic studies in a case of infant botulism show a variety of abnormalities including tetanic and post‐tetanic facilitation (PTF) of the small single evoked muscle action potential. The enlarged amplitude of the single evoked muscle action potential following a 10‐second tetanic nerve stimulation persisted up to 21 minutes. The prolongation of PTF is a unique feature of botulism.
