1. Heart and lung function - in health and disease : methodological studies in clinical physiology
Sammanfattning : The human heart and lungs constitute an intricate and dynamic system. Various clinical physiological examinations can be used to evaluate cardio-pulmonary function and identify abnormalities. Thus, it is important to understand how normal physiology presents, to be able to identify pathological findings. LÄS MER
2. Women's hearts : ischaemic heart disease and stress management in women
Sammanfattning : 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.

3. Physiological recovery from night-call duty - a field study of physicians
Sammanfattning : 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. LÄS MER
4. Idiopathic environmental intolerance attributed to electromagnetic fields : physiological and psychological aspects
Sammanfattning : 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.

5. Respiratory Sinus Arrhythmia and Emotion : Effects of pictorial stimuli and state anxiety
Sammanfattning : 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. LÄS MER
