1. Cellular electrophysiological modulation in chronic atrial fibrillation - Studies with magnesium and GIK solution
Abstract : 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. READ MORE

2. ATRIOVENTRICULAR CONDUCTION in Patients with Paroxysmal Supraventricular Tachycardias
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.

3. Cardiac electrophysiologic effects of mental stress
Abstract : Background: Mental stress may trigger serious arrhythmias. Mental stress tests cause significant increases in heart rate, blood pressure and cardiac output. When beta-adrenergic inhibition is considered for secondary antiarrhythmic prophylaxis beta1 selective agents are often preferred because of less adverse reactions. READ MORE

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

5. Hyperthyroidism and its impact on cardiovascular disease : with special emphasis on atrial fibrillation
Abstract : Background: Hyperthyroidism is a common disease throughout the world, affecting 0.5%-2% of women and one-tenth as many men at some time. Graves’ disease and toxic nodular goitre are the two most common etiologies. Cardiovascular symptoms are often prominent, and atrial fibrillation (AF) is a well-known complication. READ MORE
