Enhancement of heartbeat-related brain potentials through cardiac awareness training
Abstract
Heartbeat synchronous potentials were found to be sensitive to differences in perceptual accuracy. Since heartbeat perception can be improved using appropriate training procedures, increased ability to perceive cardiac performance should also influence heartbeat-related potentials. In the present study, subjects in either of two groups had to press a button immediately after the occurrence of a heartbeat-feedback tone. Whereas the first group was given acoustical heartbeat-feedback throughout the entire training, the second group was provided with tone signals that became fainter during the course of the training phases. The better posttraining performance in heartbeat perception of the group receiving full-intensity feedback was also reflected in the evoked potentials. They differed markedly before and after training, especially between 250 to 400 ms (after the EKG-R-wave), the biggest effect being at Fz and F7. The findings are interpreted as the brain electrical reflection of an increased perception susceptibility to a cardiovascular signal occurring at about 200 ms after the R-wave.

Schandry and Weitkunat (1990) demonstrated that auditory feedback presented 130 ms after the EKG-R wave increased both cardiac accuracy and heartbeat evoked potentials on a subsequent heartbeat perception task, indicating increased interoceptive accuracy in the cardiac domain.
“Schandry and Weitkunat (1990), for example, demonstrated that auditory feedback presented 130 ms after the EKG-R wave (such that it is perceived in synchrony with the heartbeat) increased both cardiac accuracy, and heartbeat evoked potentials on a subsequent heartbeat perception task, indicating increased interoceptive accuracy in the cardiac domain.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
