Relationship between cardiovagal modulation and psychotic state in patients with paranoid schizophrenia
Abstract
Disturbed autonomic nervous system (ANS) function in schizophrenia might contribute to increased cardiovascular mortality. We obtained heart rate variability indices from 40 unmedicated schizophrenic patients and 58 matched controls. Mainly we found that patients displaying stronger psychotic symptoms as assessed by the Brief Psychiatric Rating Scale exhibit more severe cardiac ANS disturbances compared with controls.

Higher scores on the Brief Psychiatric Rating Scale (BPRS) have been correlated with lower HF-HRV and greater LF/HF ratios.
“For instance, higher scores on the Brief Psychiatric Rating Scale (BPRS) have been correlated with lower HF-HRV and greater LF/HF ratios62, indicating that patients with stronger psychotic symptoms exhibit reduced cardiovagal modulation.”

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.
