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

    University dissertation from Cardiology, Dept of Clinical Science, Lund, Lund University

    Author : Yan Huo; Lund University.; Lunds universitet.; [2015]
    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.

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

    University dissertation from Faculty of Medicine, Lund University

    Author : Rasmus Havmöller; Lund University.; Lunds universitet.; [2009]
    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

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

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Jonas Carlson; Lund University.; Lunds universitet.; [2005]
    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.

  5. 5. Quasiparticles in the Quantum Hall Effect

    University dissertation from Stockholm : Fysikum

    Author : Janik Kailasvuori; Stockholms universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum Hall effect; quasiparticles; noncommutative Chern-Simons theory; nonabelian statistics; thin torus; p-wave superconductivity; topology; index theory; effective gauge fields; NATURAL SCIENCES Physics Condensed matter physics; NATURVETENSKAP Fysik Kondenserade materiens fysik;

    Abstract : The fractional quantum Hall effect (FQHE), discovered in 1982 in a two-dimensional electron system, has generated a wealth of successful theory and new concepts in condensed matter physics, but is still not fully understood. The possibility of having nonabelian quasiparticle statistics has recently attracted attention on purely theoretical grounds but also because of its potential applications in topologically protected quantum computing.
