  1. 1. Chronic atrial fibrillation in man. Activation, organisation and characterisation

    Författare :Magnus Holm; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ECG spectral analysis; Preferential conduction; Organisation; Conduction velocity; Refractoriness; Mechanisms; Activation pattern; Chronic; Fibrillation; Human; Atrium; Open-heart surgery; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Chronic atrial fibrillation (CAF), with a prevalence progressively increasing with age, is one of the most common cardiac arrhythmias in man and associated with increased morbidity and mortality. Previous studies have shown that, in animals as well as in man, experimental atrial fibrillation is based on different types and dimensions of intra-atrial electrical re-entry. LÄS MER

  4. 3. Greeting the visitor : A contextualising study of fauces-mosaics in Pompeii

    Författare :Fanny Kärfve; Pompeji - en uppdatering-lup-obsolete-HT_760; []
    Nyckelord :HUMANIORA; HUMANITIES; Pompeii; mosaics; fauces; entrances; atrium-houses; Interior decoration; display; emulation; protection; liminal spaces; mortar-floors;

    Sammanfattning : The focus for this study is the collection of mosaic-floors that adorn the entrances, fauces, to atrium-houses around Pompeii. The aim is to further our understanding of the Roman view of transitional spaces, in this case the private house-entrance between the inside and the outside world. LÄS MER

  5. 4. Climate and Energy Use in Glazed Spaces

    Författare :Maria Wall; Institutioner vid LTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; design tool; field measurements; calculations; thermal comfort; cooling; heating; energy requirement; solar energy; climate; atrium buildings; glazed spaces;

    Sammanfattning : Glazed spaces ranging from small glazed verandas to large atrium buildings have become a common feature in architecture. A glazed space is greatly affected by aspects of the outside climate such as insolation and temperature. LÄS MER

  7. 5. Left atrial function in health and disease

    Författare :Mark Henein; Per Lindqvist; Stellan Mörner; Reidar Winter; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left atrium; Doppler echocardiography; atrial interaction; atrial pressure;

    Sammanfattning : The Objectives of this thesis are:1) To study possible atrial interaction in patients with right and left ventricular outflow tract obstruction due to significant pulmonary (PS) and aortic valve stenosis (AS), respectively.2) To assess left atrial (LA) intrinsic myocardial function and its relationship to indirect measures of left ventricular (LV) filling pressures in patients with paroxysmal atrial fibrillation (PAF).
