Application of computer averaging techniques to the study of learned volitive heartbeat control.
Research on the acquisition of conscious cardiovascular control (Yellin 1984, 1986) utilized computer averaging of electrocardiographic (ECG) cycles to demonstrate and document precise, reliable and sustainable time-locking of heartbeat to external stimuli on demand. ECG cycles were treated as evoked responses, and successive epochs were summated, beginning with Zeitgeber-stimulus (ZS) onset, and with the duration of each epoch equaling the ZS's interstimulus interval. Cardiac synchrony was exhibited by event-modulated (time-locked) cardiac responses (EMCRs) and in average ECGs.
