Heart rate variability in schizophrenia: A comparative analysis before and after electroconvulsive therapy.

Aim: The aim of this study was to investigate autonomic nervous system imbalance in schizophrenia by comparing heart rate variability (HRV) between patients with schizophrenia and healthy controls, and to assess changes in HRV in patients before and after electroconvulsive therapy (ECT).

Methods: HRV was compared between patients with schizophrenia ( = 17) and age- and gender-matched healthy controls ( = 34). Changes in HRV were also assessed in patients pre- and post-ECT.

Nutritional counseling needs of patients with mental disorders in psychiatric care: A cross-sectional survey.

Background: The exploration of diet and nutrition as they relate to mental health and psychiatric disorders is a developing field. Anxiety, depression, and pharmacological treatments used to treat these disorders are likely to have side effects that induce decreases in activity and irregular eating habits, resulting in persistent nutritional imbalance. Unhealthy dietary patterns are associated with an increased risk of developing physical and mental health conditions.

Heart rate response to orthostatic challenge in patients with dementia with Lewy bodies and Alzheimer's disease.

Background: To elucidate the differences in autonomic dysfunction between dementia with Lewy bodies (DLB) and Alzheimer's disease using a simple and convenient method, we investigated the heart rate response to orthostatic challenge.

Methods: Ninety-seven people participated in this cross-sectional study, and data from 26 DLB patients, 29 Alzheimer's disease patients, and 25 healthy elderly individuals were analysed. Participants underwent postural changes, including 5 min in a supine position, 1 min in a sitting position, and 3 min in an orthostatic position.

Predicting postictal suppression in electroconvulsive therapy using analysis of heart rate variability.

Background: Postictal suppression on an electroencephalogram (EEG) represents electrical silence during electroconvulsive therapy (ECT) and has been considered as a key feature associated with the efficacy of treatment. The present study aimed to predict postictal suppression using heart rate variability (HRV).

Methods: Participants comprised 21 consecutive patients with depression who underwent bilateral pulse wave ECT.

Changes in cardiac autonomic nervous system activity during a course of electroconvulsive therapy.

Aim: Although electroencephalogram (EEG) seizure duration and seizure threshold change during a course of electroconvulsive therapy, the mechanisms by which these factors influence heart rate during subsequent electroconvulsive therapy sessions are currently unclear. In the current study, we investigated changes in heart rate during electroconvulsive therapy.

Methods: We recorded electroencephalography and electrocardiography during electroconvulsive therapy in 12 patients with major depressive disorder.

Is prolongation of corrected QT interval associated with seizures induced by electroconvulsive therapy reduced by atropine sulfate?

Background: Electrocardiogram abnormalities have been reported during electroconvulsive therapy (ECT). A corrected QT interval (QTc) prolongation indicates delayed ventricular repolarization, which can trigger ventricular arrhythmias such as torsade de pointes (TdP). We examined the QTc changes during generalized tonic-clonic seizures induced by ECT, and the effects of atropine sulfate on these QTc changes.
