  2. 1. Atrial Conduction and P-wave Characteristics: From histology to electrophysiology

    Author : Yan Huo; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; Sinus rhythm; Histology; Electrophysiology; Human; P-wave Morphology; Variability of P-wave morphology; P-wave duration;

    Abstract : P-wave morphology reflects the projection of the depolarization vector on the electrocardiogram (ECG)lead axes in three-dimentional space and reflects both right and left atrial activation. The main purpose of current thesis was to explore the internal logic between the atrial conduction properties, including intra- and inter- atrial conduction, and P-wave characteristics from the level of histology to electrophysiology.

  4. 2. Observations of Interatrial Conduction in Healthy Individuals Using Signal-averaged P-wave ECG: A Clinical Perspective

    Author : Rasmus Havmöller; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal-averaged; interatrial conduction; orthogonal; P-wave; ECG; healthy;

    Abstract : Disturbances of interatrial conduction are linked to supraventricular arrhythmias. Previous studies have shown that these disturbances can be detected non-invasively as distinctive appearances of the orthogonal P wave using signal-averaged P-wave analysis (PSAECG). READ MORE

  6. 4. Exploration of Supraventricular Conduction with respect to Atrial Fibrillation. Methodological Aspects on Selected Techniques

    Author : Jonas Carlson; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Signal processing; Kardiovaskulära systemet; Cardiovascular system; Correlation Function Analysis; Transformation; Modeling; P wave Morphology; Signal; Conduction; Human; Atrial Fibrillation; Signalbehandling; Electrocardiography;

    Abstract : 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.

  7. 5. Clinical evaluation and implications of left atrial remodeling in atrial fibrillation : From silent cerebral lesions and atrial stunning to novel electrocardiographic tools for prediction of arrhythmia outcome

    Author : Panagiotis Arvanitis; Carina Blomström-Lundqvist; Mårten Rosenqvist; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; left atrial remodeling; recurrence; new-onset; silent cerebral lesions; white matter hyperintensities; cardioversion; pulmonary vein isolation; risk factors; electrocardiographic predictors; P-wave indices; machine learning; predictive models; Covid-19;

    Abstract : Atrial fibrillation (AF) is the most common cardiac arrhythmia. Left atrial (LA) remodeling and reverse remodeling are associated with cerebral involvement and cognitive function (CF) changes. Risk stratification for AF related outcomes is essential in the management of patients with AF. READ MORE
