2. 1. Aortic valvular flow : a clinical and experimental doppler echocardiographic study

   Author : Birgitta Janerot Sjöberg; Ihlen Halfdan; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Aortic blood velocity determination by ultrasound Doppler is a safe and valuable tool when evaluating patients with heart disease. The time-course of the velocity signal can be used for detemnining left ventricular function. READ MORE

4. 2. Towards Heart Rate Variability Tools in P-Health : Pervasive, Preventive, Predictive and Personalized

   Author : Farhad Abtahi; Kaj Lindecrantz; Birgitta Janerot Sjöberg; Fernando Seoane; Annette Bruchfeld; Metin Akay; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heart Rate Variability; Cholinergic Anti-inflammatory Pathway; Autonomic Nervous System; Vagal activity; Biofeedback; Gamification; Serious Gaming; Inflammatory Markers; Raspberry PI; Medical Technology; Medicinsk teknologi;

   Abstract : Heart rate variability (HRV) has received much attention lately. It has been shown that HRV can be used to monitor the autonomic nervous system and to detect autonomic dysfunction, especially vagal dysfunction. Reduced HRV is associated with several diseases and has also been suggested as a predictor of poor outcomes and sudden cardiac death. READ MORE

5. 3. Cardiovascular response to hyperoxemia, hemodilution and burns : a clinical and experimental study

   Author : Zoltan Bak; Birgitta Janerot Sjöberg; Robert Hahn; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anesthesia; general; Burns; Echocardiography; transesophageal; Hemodilution; emodynamic processes; Hyperoxia; Intensive care; Intensivvård;

   Abstract : The last decades less invasive monitoring and analytical tools have been developed for the evaluation of myocardial mechanics in clinical praxis. In critical care, these are longed-for complements to pulmonary artery catheter monitoring, additionally offering previously inaccessible information. READ MORE

6. 4. Exploring Polymer-Shelled Microbubbles: Detection Modeling and Application

   Author : Hongjian Chen; Dmitry Grishenkov; Birgitta Janerot-Sjöberg; Tomas Jansson; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ultrasound contrast agent; polymer-shelled microbubble; ultrasound imaging; contrast pulse sequence; microbubble model; hydrodynamic cavitation; Technology and Health; Teknik och hälsa;

   Abstract : Ultrasound imaging (US) is widely used in clinical practice. Given the low cost and easy access to the ultrasound machine, US has a great potential to improve the health care condition for the majority of the population in the world. The US could be significantly improved by injecting ultrasound contrast agents to opacify the bloodstream. READ MORE

7. 5. Assessment of Valvular Aortic Stenosis by Signal Analysis of the Phonocardiogram

   Author : Ghareh Baghi Ghareh Baghi; Per Ask; Birgitta Janerot Sjöberg; Urban Wiklund; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Aortic stenosis (AS) is one of the most prevalent valvular heart diseases in elderly people. According to the recommendations of both the American Heart Association and the European Society of Cardiology, severity assessment of AS is primarily based on echocardiographic findings. READ MORE
