2. 1. Imaging and modeling the cardiovascular system

   Author : Elira Maksuti; Michael Broomé; Anna Bjällmark; Matilda Larsson; Martin Ugander; Patrick Segers; KTH; Karolinska Institutet; Karolinska Institutet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cardiac pumping; diastolic function; hemodynamics; modeling; simulation; arterial stiffness; ultrasound; shear wave elastography.; Medical Technology; Medicinsk teknologi; Cardiac pumping;

   Abstract : Understanding cardiac pumping function is crucial to guiding diagnosis, predicting outcomes of interventions, and designing medical devices that interact with the cardiovascular system.  Computer simulations of hemodynamics can show how the complex cardiovascular system is influenced by changes in single or multiple parameters and can be used to test clinical hypotheses.

4. 2. User Modeling for Adaptive Virtual Reality Experiences : Personalization from Behavioral and Physiological Time Series

   Author : Luis Quintero; Uno Fors; Lijffijt Jefrey; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; virtual reality; VR; machine learning; ML; user modeling; personalization; wearable; heart rate; HRV; biosensors; movement; behavioral; user experience; UX; spatial computing; metaverse; extended reality; XR; data- och systemvetenskap; Computer and Systems Sciences;

   Abstract : Research in human-computer interaction (HCI) has focused on designing technological systems that serve a beneficial purpose, offer intuitive interfaces, and adapt to a person's expectations, goals, and abilities. Nearly all digital services available in our daily lives have personalization capabilities, mainly due to the ubiquity of mobile devices and the progress that has been made in machine learning (ML) algorithms.

5. 3. Computer-based modeling and simulation in the analysis of cardiac arrhythmias and cardiac pacing

   Author : Hans Åhlfeldt; Linköpings universitet; []
   Keywords : arrhythmogenic mechanisms; modulated parasystole; phase response curve; pacemaker follow-up; modeling; simulation; MEDICINE; MEDICIN;

   Abstract : Most systems for ECG analysis deal with QRS classification and arrhythmia detection but do not address the problem of finding the underlying mechanism responsible for the manifest arrhythmia. Although it is possible to distinguish among different arrhythmogenic mechanisms on the cellular level, it is far more difficult in the clinic based on ECG recordings. READ MORE

6. 4. Signal Modeling and Detection in Nephrologic and Cardiac Applications

   Author : Kristian Solem; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heart rate turbulence HRT ; Heart rate variability HRV ; Electrocardiogram ECG ; Pulse oximetry.; Biomedical signal processing; Intradialytic hypotension; Hemodialysis; Ectopic beats;

   Abstract : This doctoral thesis is comprised of five parts in the field of biomedical signal processing with focus on methods for use in hemodialysis as well as in cardiac applications. The problem of predicting hypotension is the main concern in the parts were data from patients undergoing hemodialysis are used. READ MORE

7. 5. Exploration of Supraventricular Conduction with respect to Atrial Fibrillation. Methodological Aspects on Selected Techniques

   Author : Jonas Carlson; Kardiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Signal processing; Kardiovaskulära systemet; Cardiovascular system; Correlation Function Analysis; Transformation; Modeling; P wave Morphology; Signal; Conduction; Human; Atrial Fibrillation; Signalbehandling; Electrocardiography;

   Abstract : Atrial fibrillation is the most common cardiac arrhythmia that demands medical attention. Computer-based detailed analysis of cardiac electrical signals from healthy subjects and patients with a history of atrial fibrillation has become an important tool in the further clarification of this disease.
