    Abstract : Acute myocardial infarction (AMI), caused by ischaemic heart disease (IHD), is a leading cause of death in both men and women in the western society. Hypertension, diabetes, and smoking are examples of well-known risk factors of IHD, but also there are psychosocial factors, such as stress, vital exhaustion (unusual fatigue, irritability, and demoralization) and depression that have been associated with an increased risk in both genders.

  2. 2. Physiological recovery from night-call duty - a field study of physicians

    University dissertation from Department of Laboratory Medicine, Lund University

    Author : Birgitta Malmberg; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HRV; Acitwatch; night-call; anaesthesiologist; sleep; working time;

    Abstract : Abstract Physicians’ work on night-call entails long and stressful working hours with high demands and disrupted sleep. Incomplete recovery is considered to be the most important link between acute physiological stress reactions, shift work and chronic health effects. READ MORE

  3. 3. Idiopathic environmental intolerance attributed to electromagnetic fields physiological and psychological aspects

    University dissertation from Umeå : Yrkes- och miljömedicin

    Author : Amanda Johansson; Lena Hillert; [2008]
    Keywords : electrical hypersensitivity; EHS; mobile phone; MP; heart rate variability; HRV; provocation study; radiofrequency field; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : This thesis aims to increase the knowledge on people with symptoms attributed to electromagnetic fields (EMF) by investigating the effects of EMF exposure and by additional description of the heterogeneous group of people reporting EMF-related symptoms.The effect of mobile phone (MP)-like radio frequency (RF) fields on symptoms, autonomic nervous system (ANS) parameters, short-term memory, and reaction time in persons with MP-related symptoms (MP participants) was investigated in a provocation study.

  4. 4. Respiratory Sinus Arrhythmia and Emotion: Effects of pictorial stimuli and state anxiety

    University dissertation from Department of Psychology, Lund University

    Author : Peter Jönsson; [2005]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psykologi; Psychology; state anxiety; emotion; HRV; heart rate variability; RSA; Respiratory sinus arrhythmia;

    Abstract : Respiratory sinus arrhythmia (RSA) refers to heart rate variations due to respiration, which results from parasympathetic nervous system activity mediated via the tenth cranial nerve, the vagus. Thus, the magnitude of RSA is considered as an index of cardiac vagal tone. This thesis explored RSA during emotional responding in healthy women and men. READ MORE

  5. 5. Modelling and Inference using Locally Stationary Processes : Biomedical applications

    University dissertation from Lund University, Faculty of Science, Centre for Mathematical Sciences, Mathematical Statistics

    Author : Rachele Anderson; [2017-11]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Modelling of Time-Varying Signals; Locally Stationary Processes; Statistical Inference; Time-frequency Estimation; Regression; EEG Signals; HRV Signals;

    Abstract : This thesis considers statistical methods for non-stationary signals, specifically stochastic modelling, inference on the model parameters and optimal spectral estimation. The models are based on Silverman’s definition of Locally Stationary Processes (LSPs). READ MORE
