2. 1. Novel Approaches to ECG-Based Modeling and Characterization of Atrial Fibrillation

   Author : Frida Sandberg; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HMM; ECG; Biomedical Signal Processing; Time-Frequency Analysis; Atrial Fibrillation; Sample Entropy; AV modeling;

   Abstract : This thesis deals with signal processing algorithms for analysis of the electrocardiogram (ECG) during atrial fibrillation (AF). Such analysis can be used for diagnosing patients, and for monitoring and predicting their response to various treatment. READ MORE

4. 2. Sympathetic neural blockade during regional analgesia : Clinical investigations in man

   Author : Lars-Åke Malmqvist; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Different opinions exist concerning the extent and intensi-ty of the concomitant sympathetic block during regional blockade, and how to test the completeness of the sympathetic blockade. Studies were performed on 21 volunteers and 162 patients scheduled for surgery of the urogenital area or surgery for varicose v-eins, and chronic pain patients. READ MORE

5. 3. Atrial fibrillation – on its trigger mechanisms, risks and consequences

   Author : Dritan Poci; Göteborgs universitet; []
   Keywords : acute coronary syndromes; atrial fibrillation; AV junctional ablation; CHADS2 score; electrical cardioversion; mortality; stroke; trigger mechanisms;

   Abstract : Background: Atrial fibrillation (AF) frequently impairs quality of life, but in long-term it is associated with an increased morbidity and mortality. Persistent AF may cause changes in the sinus node function, and if converted to sinus rhythm (SR), there is a substantial risk of recurrence of AF. READ MORE

6. 4. Acute coronary syndrome and cardiac arrest in the elderly

   Author : Berglind Libungan; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Elderly; Acute Coronary Syndrome; Cardiac Arrest;

   Abstract : The elderly are currently the fastest growing segment of clinical practice but the quality and quantity of the underlying scientific evidence to guide treatment is limited. In this thesis five different studies investigating different aspects of geriatric cardiac care are presented. READ MORE

7. 5. Clinical evaluation and implications of left atrial remodeling in atrial fibrillation : From silent cerebral lesions and atrial stunning to novel electrocardiographic tools for prediction of arrhythmia outcome

   Author : Panagiotis Arvanitis; Carina Blomström-Lundqvist; Mårten Rosenqvist; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; left atrial remodeling; recurrence; new-onset; silent cerebral lesions; white matter hyperintensities; cardioversion; pulmonary vein isolation; risk factors; electrocardiographic predictors; P-wave indices; machine learning; predictive models; Covid-19;

   Abstract : Atrial fibrillation (AF) is the most common cardiac arrhythmia. Left atrial (LA) remodeling and reverse remodeling are associated with cerebral involvement and cognitive function (CF) changes. Risk stratification for AF related outcomes is essential in the management of patients with AF. READ MORE
