Heartbeat evoked potentials (HEP): topography and influence of cardiac awareness and focus of attention

Montoya, Pedro, Schandry, Rainer, Müller, Achim·1993·Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section

Abstract

Heartbeat evoked potentials (HEP) were recorded from good and poor heartbeat perceivers under two conditions differing in focus of attention. Under the first condition (ATT), subjects were instructed to count their heartbeats. Under the second condition (DIS), subjects were distracted from their heartbeats by having them count external tones. Electrical brain activity was recorded from 19 electrodes. EEG epochs were triggered by the R wave of the EKG. Analyses of variance yielded a significant difference for focus of attention in HEP amplitudes at central electrodes (Cz, C3, and C4) in the latency range 350-550 msec post R wave. No significant differences occurred between good and poor perceivers. The interaction between the Group and Condition factors was significant at F4, C4 and T6. The potential map of good perceivers showed a fronto-temporal positivity, which was reduced in poor perceivers. Our data suggest that paying attention to an internal event such as the heartbeat can modify the cortical evoked response associated with that event.

  • HEP results are consistent with previous investigations concerning the neural response to heartbeats, in that effects were typically found between 200 ms and 500 ms after ECG R peaks.

    “Our HEP results are consistent with previous investigations concerning the neural response to heartbeats, in that the effects were typically found to exist between 200 ms and 500 ms after ECG R peaks (Montoya et al. 1993;Pollatos and Schandry 2004).”

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.
