1. Cellular electrophysiological modulation in chronic atrial fibrillation - Studies with magnesium and GIK solution
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
Sammanfattning : Aim: To non-invasively detect and explore the changes in atrial fibrillatory cycle length (i.e. changes in the atrial refractory period) in humans with chronic atrial fibrillation (CAF) following autonomic modulation and pharmacological intervention. LÄS MER
Sammanfattning : Chronic atrial fibrillation (CAF), with a prevalence progressively increasing with age, is one of the most common cardiac arrhythmias in man and associated with increased morbidity and mortality. Previous studies have shown that, in animals as well as in man, experimental atrial fibrillation is based on different types and dimensions of intra-atrial electrical re-entry. LÄS MER
Sammanfattning : The subject of this thesis is the clinical use of the oesophageal electrode in electrocardiology. The three areas covered are oesophageal electro- cardiography, the biophysics of transoesophageal atrial stimulation (TAS) and the clinical utility of TAS. The literature is reviewed with respect to these areas. LÄS MER
Sammanfattning : 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. LÄS MER
