2. 1. Focal atrial tachycardia : Insights concerning the arrhythmogenic substrate based on analysis of intracardiac electrograms and inflammatory markers

   Author : Ioan Liuba; Gerhard Hindricks; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Background: Focal atrial tachycardias are tachycardias characterized by a radial spread of activation from a discrete area of the atrial myocardium. They account for 10-15% of supraventricular tachycardias and are generally poorly responsive to pharmacological treatment. The pathophysiologic substrate of these arrhythmias remains poorly understood. READ MORE

4. 2. ATRIOVENTRICULAR CONDUCTION in Patients with Paroxysmal Supraventricular Tachycardias

   Author : Shaowen Liu; Kardiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Kardiovaskulära systemet;

   Abstract : This thesis concerns retrospective and prospective studies of the atrioventricular (AV) conduction properties in patients with cardiac arrhythmias. The objectives of the retrospective studies were to further delineate the sex distribution in patients with Wolff-Parkinson-White syndrome (WPW) and AV nodal reentrant tachycardia (AVNRT) and to determine the underlying mechanisms of the differences in sex distribution, to investigate the relationship between the conduction properties of normal and accessory AV pathway, and to evaluate their conduction properties with respect to accessory pathway location.

5. 3. Conduction Disturbances in Patients with Atrial Fibrillation

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

   Abstract : 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. READ MORE

6. 4. Atrial fibrillation : treatment, associated conditions and quantification of symptoms

   Author : Niklas Höglund; Steen Jensen; Milos Kesek; Karl Franklin; Juhani Koistinen; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; cardioversion; atorvastatin; high-sensitivity C-reactive protein; symptoms; sleep apnea; kardiologi; Cardiology;

   Abstract : Background: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia. There is a need for new pharmacological treatment strategies since the current antiarrhythmic drugs have a modest efficacy and may have severe side effects. Cardioversion (CV) of AF offers an opportunity to study related conditions in sinus rhythm (SR) and during AF. READ MORE

7. 5. Sex and gender differences in patients undergoing ablation of atrial arrhythmias

   Author : Carina Carnlöf; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Background: Women and men differ in the prevalence of arrhythmias. Furthermore, there are sex and gender differences in referral for ablation, symptom severity, health-related quality of life (HRQOL), functional impairment and response to treatment, risk factors, and outcomes.
