The interplay of heart rate variability and ventricular repolarization parameters in the obese state: a review.

The impact of obesity on heart rate variability (HRV) and ventricular repolarization, both vital indicators of cardiovascular health, is the focus of this review. Obesity, measured by BMI, waist circumference, and waist-to-hip ratio, significantly increases cardiovascular disease (CVD) risk due to structural and autonomic heart changes. Findings show that obese individuals exhibit prolonged QT and Tpeak-to-Tend (Tpe) intervals, suggesting delayed ventricular recovery and greater arrhythmia risk.

Analysis of ventricular repolarization parameters and heart rate variability in obesity: a comparative study.

Obesity is associated with dysfunctional electrocardiographic and cardiac autonomic parameters, which may lead to increased cardiovascular morbidity. Novel electrocardiographic repolarization markers such as Tpeak-Tend (Tpe) interval have not yet been deeply studied in obese patients. We aimed to investigate the association between ventricular repolarization parameters and heart rate variability (HRV) and how they are affected by changes occurring in the cardiac autonomic nervous system.

Preferential Impairment of Auditory Working Memory in Long COVID: An Observational Study of Undergraduate Medical Students.

Background Long COVID is a multisystem condition with prolonged symptoms that develop after recovery from the COVID-19 infection, often following a mild infection. Few studies have been conducted on cognitive function among medical students after recovery from mild COVID-19 This study aimed to assess the attention span and working memory (WM) capacity of medical students after six months of recovery. Methods A cross-sectional study was performed on 17 young adult medical students who had suffered a mild COVID-19 infection at least six months prior.

Change in auditory and visuospatial working memory with phases of menstrual cycle: A prospective study of three consecutive cycles.

The menstrual cycle is a well-known physiological model used to study working memory (WM) function. The present study examined auditory and visuospatial WM during proliferative and secretory phases of three consecutive menstrual cycles.Forty young adult females with a mean age of 23.
