16. The oesophageal route in clinical electrocardiology
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
17. Conduction Disturbances in Patients with Atrial Fibrillation
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
18. Cardiac muscle injury in children and experimental animals. Reflections in ECG, especially high-resolution electrocardiography
Sammanfattning : Background and Methods: Signal-averaging ECG (SAECG), a bioelectrical processing method, is a further development of the conventional ECG. SAECG can detect voltage potentials in the microvolt range and provide a noise-reduced determination of QRS duration. Extended frequency spectra can be analysed. LÄS MER
19. Epicardial ablation - a study evaluating thoracoscopic and surgical ablation procedures for patients with intractable atrial fibrillation
Sammanfattning : Atrial fibrillation (AF) is a common condition, increasing in prevalence with age. Symptoms can be severe and quality of life is affected in patients suffering from AF. Treatment regimes aim to alleviate symptoms through rate or rhythm control. LÄS MER
20. Exploration of Supraventricular Conduction with respect to Atrial Fibrillation. Methodological Aspects on Selected Techniques
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.
