10 Ss showed reliable accuracy in voluntarily producing electrocardiogram R waves within precise time intervals after repetitive stimuli. Ss' ability accurately to vary the timing of the R wave occurrences within the interstimulus interval is evidence that the heartbeats were not driven by the repetitive stimuli but were under the precise voluntary control of Ss.
