  1. 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

  2. 2. Assessing Symptom Burden and Health-Related Quality of Life in patients living with arrhythmia and ASTA : Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmia

    Author : Ulla Walfridsson; Anna Strömberg; Kristofer Årestedt; Nils Edvardsson; Linköpings universitet; []
    Keywords : Arrhythmias; Symptom burden; Health-Related Quality of Life; Patient-reported outcomes; Validation; Disease-specific questionnaire;

    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. 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

    Author : Christer Gottfridsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal-averaged ECG; ventricular tachycardia; ventricular fibrillation; late potentials; spectral turbulence; bundle branch block;

    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. 4. The oesophageal route in clinical electrocardiology

    Author : Steen Pehrson; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; oesophageal electrocardiogram; cardiac pacing; Transoesophageal stimulation; arrhythmias; non-invasive electrophysiology; atrial fibrillation; supraventricular tachycardia; Kardiovaskulära systemet;

    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. 5. Studies on malignant ventricular tachyarrhythmias and their treatment with an implantable defibrillator

    Author : Bengt Sandstedt; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Implantable cardioverter defibrillator; ventricular fibrillation; ventricular tachycardia; predischarge test; defibrillation threshold; discrimination; electrogram morphology; aortic stenosis; hypertrophy; noradrenalin;

    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
