Altered Heart Rate Variability During Rest in Schizophrenia: A State Marker.

Background: Autonomic nervous system (ANS) imbalance has been reported in a number of psychiatric disorders such as depression, schizophrenia, panic disorder, etc. Autonomic dysfunction in schizophrenia has been associated with the symptoms and manifestation of psychosis. Heart rate variability (HRV) as a tool has been widely used to assess ANS activity and the effect of disease on the sympathovagal balance.

Applicability of Concept Maps to Assess Higher Order Thinking in the Context of Indian Medical Education: An Analytical Study in the Subject of Physiology.

Introduction: Concept mapping is a multidimensional tool that has been put to little use in India. We designed this study to check its applicability for assessing higher-order thinking in the subject of Physiology.

Methods: This interventional analytical study was carried out among 65 students of Phase I of MBBS in the year 2021.

Effect of Resonance Breathing on Heart Rate Variability and Cognitive Functions in Young Adults: A Randomised Controlled Study.

Introduction: Heart rate variability (HRV) is an important physiological biomarker of wellbeing, mood, and adaptation, and hence improvements in HRV signify improved health, mood, and adaptation to stress. Resonance breathing has consistently been shown to increase HRV, mood, and adaptability. The study investigated the effects of four-week training of resonance breathing in young adults on HRV, stress, and cognition functions.

Effect of controlled deep breathing on psychomotor and higher mental functions in normal individuals.

Objective: The present study was conducted to assess the effect of controlled deep breathing on psychomotor and higher mental functions.

Methods: 100 normal healthy subjects (52 females and 48 males, age range - 18 to 25 years) participated in the study. Each subject acted as his or her own control.

Effect of Sub Maximal Dynamic and Static Exercises on QTc interval in Healthy Young Men.

Introduction: The QTc interval depends largely on cardiac repolarization since the duration of cardiac depolarization is fairly constant in the normal heart. QTc at rest as well as during exercise has many clinical implications. In this study, we have compared the relative effects of dynamic and static exercise on QTc.
