1. 1. Electrocardiographic Imaging of Myocardial Ischemia, Infarction and Scar: Correlation with SPECT, MRI and Arrhythmias

   Författare :David G Strauss; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrocardiography; Imaging; Arrhythmias; Ischemia; Infarction; Cardiomyopathy; SPECT; MRI;

   Sammanfattning : This thesis focuses on the development and testing of electrocardiographic (ECG) methods to diagnose and characterize myocardial ischemia, infarction and fibrosis (scar). The goal is to provide improved decision support to physicians regarding the optimal selection of patients for two costly, invasive therapies – percutaneous coronary intervention (PCI) for patients with acute myocardial infarction (MI) and implantable cardioverter defibrillators (ICDs) for patients with heart failure and reduced left ventricular ejection fraction (LVEF).

3. 2. Novel approaches using electrocardiographic imaging for early detection of ARVC in patients and relatives and symptoms preceding sudden death

   Författare :Varvara Kommata; Carina Blomström-Lundqvist; Elena Sciaraffia; Domenico Corrado; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arrhythmogenic Right Ventricular Cardiomyopathy; diagnosis; gene carriers; body surface mapping; electrocardiographic imaging; sudden cardiac death; Cardiology; Kardiologi; Cardiology; Kardiologi;

   Sammanfattning : Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) is an inherited disease of the myocardium, predominantly affecting the right ventricle (RV). Arrhythmias are common among patients with the disease and Sudden Cardiac Death (SCD) can occur even in early stages. LÄS MER

4. 3. Nuclear Magnetic Resonance for Diffusion Imaging Development and evaluation of spin-echo-based pulse sequences for in vivo studies of water self-diffusion

   Författare :Sara Brockstedt; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perfusion fraction; electrocardiographic triggering; segmented EPI SEPI ; echo-planar imaging EPI ; fast spin-echo FSE ; spin-echo SE ; navigator echoes; phase corrections; diffusion; Magnetic resonance; MRI; ischaemic stroke; Medicine human and vertebrates ; Medicin människa och djur ;

   Sammanfattning : The interest in diffusion imaging with nuclear magnetic resonance techniques has increased during the last few years. The main reason is the possibility of early diagnosis of acute ischaemic stroke, at a time when conventional MR techniques and computerised tomography fail. LÄS MER

5. 4. 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

   Författare :Panagiotis Arvanitis; Carina Blomström-Lundqvist; Mårten Rosenqvist; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 5. Electrocardiographic characterization of myocardial scar in presence of conduction abnormality

   Författare :Björn Wieslander; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Presence, extent and localization of myocardial scar constitute prognostic clinical information that can influence therapeutical decisions. Cardiovascular magnetic resonance imaging with late gadolinium enhancement (CMR-LGE) is the preferred method to image myocardial scar in vivo but is resource intensive and has contraindications.
