  2. 1. Autonomic cardiac control in long QT syndrome : clinical studies of arrhythmogenic triggers

    Author : Anna Lundström; Annika Rydberg; Urban Wiklund; Håkan Eliasson; Jacob Tfelt-Hansen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT syndrome; pediatrics; exercise; Holter; water immersion; arrhythmia; clinical physiology; ECG; heart rate variability; heart rate response; cardiovascular disease; hjärt- och kärlforskning; kardiologi; Cardiology; pediatrik; Pediatrics;

    Abstract : Background: Long QT syndrome (LQTS) is an inherited cardiac disease characterized by prolonged cardiac repolarization and an increased risk for life-threatening arrhythmias. These arrhythmias are typically triggered by adrenergic stimuli, such as physical activity and intense emotions, implicating that the sympathetic part of the autonomic nervous system (ANS) is involved in arrhythmogenesis.

  4. 2. Cellular electrophysiological modulation in chronic atrial fibrillation - Studies with magnesium and GIK solution

    Author : Max Ingemansson; Lunds universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Action potential duration; Atrial cycle length; Atrial remodelling; Autonomic nervous system; AV-nodal; Conduction velocity; GIK; Magnesium; Resting membrane potential.; Refractoriness; Atrial fibrillation; Cardiovascular system; Kardiovaskulära systemet;

    Abstract : Although chronic atrial fibrillation (CAF) is the most common sustained cardiac arrhythmia in man, the mechanisms involved in its progressive course are still not fully understood. Recent studies have verified an electrical remodelling of the atrial myocardium that may be responsible for the electrophysiological disturbances known to exist in the fibrillating atria. READ MORE

  5. 3. Gastrointestinal disturbances in hereditary transthyretin amyloidosis

    Author : Jonas Wixner; Ole B Suhr; Intissar Anan; Pontus Karling; Anders Rönnblom; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Autonomic Nervous Systems; Cajal Interstitial Cells; Enteric Nervous System; Familial Amyloid Polyneuropathy; Functional Gastrointestinal Disorders; Gastric Emptying; Liver Transplantation; Nutrition Status; Transthyretin Amyloidosis; medicin; Medicine;

    Abstract : BackgroundTransthyretin amyloid (ATTR) amyloidosis is a systemic disorder caused by amyloid deposits formed by misfolded transthyretin (TTR) monomers. Two main forms exist – wild-type and hereditary ATTR amyloidosis, the latter associated with TTR gene mutations. READ MORE

  6. 4. Pregnancy—A Critical Time for Mental Health : Interrogating Psychiatry with Microbiota-Gut-Brain Axis and Autonomic Nervous System Biomarkers

    Author : Mary C. Kimmel; Alkistis Skalkidou; Janet Cunningham; Emma Fransson; Samantha Meltzer-Brody; Susan Garthus-Niegel; Uppsala universitet; []
    Keywords : pregnancy; heart rate variability HRV ; microbiome; depression; anxiety; self-efficacy; cytokines; biomarkers;

    Abstract : Perinatal mood and anxiety disorders (PMADs) are common and impact the parent and child beyond the perinatal period of pregnancy and postpartum. The aim of this thesis was to study biomarkers that might reflect perinatal mental health. READ MORE

  7. 5. Heart and lung function - in health and disease : methodological studies in clinical physiology

    Author : Sofia Erelund; Nina Sundström; Urban Wiklund; Sandra Arvidsson; Bengt Johansson; Carl-Johan Carlhäll; Umeå universitet; []

    Abstract : 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. READ MORE
