1. 1. Characterisation of Atrial Electrophysiology with respect to Atrial Fibrillation - A Non-Invasive Approach

   Författare :Fredrik Holmqvist; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrocardiography; Atrial fibrillation; Human; Conduction; Signal; Spectral analysis; P wave morphology; Atrial remodelling; Cardiovascular system; Kardiovaskulära systemet;

   Sammanfattning : Atrial fibrillation (AF) is the most common form of cardiac arrhythmia encountered in clinical practice, accounting. Recent findings highlight the need for better characterisation of the arrhythmia in each patient, in order to improve patient treatment. LÄS MER

3. 2. Conduction Disturbances in Patients with Atrial Fibrillation

   Författare :Eva Hertervig; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Pulmonary Vein Potentials; Atrial Fibrillation; Conduction Disturbances;

   Sammanfattning : Background: The electrophysiological mechanisms underlying atrial fibrillation (AF) are incompletely understood. Experimental studies have shown that remodelling of the atrial myocardium is linked to the occurrence and perpetuation of AF. LÄS MER

4. 3. Secundum atrial septal defect in the adult. Clinical, haemodynamic and electrophysiological aspects

   Författare :Ulf Thilén; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; clinical outcome; atrial fibrillation; Atrial septal defect; atrial conduction; remodelling.;

   Sammanfattning : Atrial septal defect (ASD) is the most common congenital heart malformation diagnosed in adult life. In this thesis important clinical, haemodynamic and electrophysiological aspects of ASD in the adult are explored. LÄS MER

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

   Författare :Max Ingemansson; Lunds universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

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

   Författare :Jonas Carlson; Kardiologi; []
   Nyckelord :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;

   Sammanfattning : 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.
