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

2. Assessing Symptom Burden and Health-Related Quality of Life in patients living with arrhythmia and ASTA : Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmia
Abstract : Background: Health-Related Quality of Life (HRQOL) can be negatively affected in patients living with arrhythmias and many patients experience a pronounced symptom burden. The arrhythmia can cause both uncertainty and limitations, including interference with work, reluctance to perform and plan for leisure activities and leading to self-imposed restrictions in daily life situations.

3. Noninvasive characterization of patients with monomorphic ventricular tachycardia and ventricular fibrillation using the signal-averaged electrocardiogram. A study on late potentials and spectral turbulence in patients with ischemic heart disease and in healthy subjects
Abstract : Many people die suddenly from sustained ventricular tachyarrhythmias caused by ischemic heart disease, and the sudden death may be the first presentation of heart disease. If the patients at risk of ventricular tachyarrhythmia could be identified, some patients may be saved. READ MORE

4. The oesophageal route in clinical electrocardiology
Abstract : 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. READ MORE

5. Studies on malignant ventricular tachyarrhythmias and their treatment with an implantable defibrillator
Abstract : Aims: To investigate the hemodynamic, metabolic and autonomic effects of ventricular fibrillation per se during maintained circulation. To study the defibrillation threshold (DFT) and efficacy of a new and thinner ICD lead (DSP) compared with the standard lead (C). READ MORE
