1. 1. Atrial Fibrillation after Coronary Artery Bypass Surgery : A Study of Causes and Risk Factors

   Författare :Lena Jidéus; Dan Lindblom; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Atrial fibrillation; catecholamines; coronary artery bypass surgery; heart rate variability; neuropeptides; premature atrial contraction; thoracic epidural anaesthesia; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

   Sammanfattning : The aim was to study pathophysiological mechanisms and risk factors for developing atrial fibrillation (AF) after coronary artery bypass grafting (CABG), and the effect of thoracic epidural anaesthesia (TEA).The study comprised 141 patients undergoing CABG, including 45 patients randomised for TEA intra- and postoperatively.

3. 2. The important role of left atrial function parameters in clinical practice

   Författare :Ibadete Bytyci; Michael Y. Henein; Roxy Senior; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left atrial function; Left atrial compliance; left atrial stiffness; Clinical practice; kardiologi; Cardiology;

   Sammanfattning : The aim of this thesis is to evaluate the role of left atrial function in clinical practice based on the following studies:1)    Determining left atrial (LA) structure and myocardial function measurements that predict pulmonary capillary wedge pressure (PCWP).2)    Identifying predictors of exercise capacity in patients with HFpEF and right ventricle (RV) dysfunction.

4. 3. Ventricular Long Axis Function: Amplitudes and Timings : Echocardiographic Studies in Health and Disease

   Författare :Frederick Bukachi; Anders Waldenstrom; Derek Gibson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler Tissue Imaging; Ageing; coronary disease; left ventricular function; atrial contraction; electromechanical function; coronary angioplasty.; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

   Sammanfattning : Background: The ageing process not only increases the risk of coronary artery disease (CAD) but also complicates its diagnosis and treatment. It is therefore important to understand the newer concepts of cardiovascular ageing physiology as well as methods of predicting the outcomes of therapeutic options available for the elderly with severe CAD.

5. 4. Right heart function in health and disease : a doppler echocardiography and doppler tissue imaging study

   Författare :Per Lindqvist; Elsadig E Kazzam; Anders Waldenström; Lars Åke Brodin; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler tissue imaging; right ventricle; cardiac catheterisation; isovolumic relaxation; isovolumic contraction; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

   Sammanfattning : Background: It is well known that performance of the right ventricle (RV) determines exercise capacity and may confer prognostic information in different cardiopulmonary diseases. To allow optimal patient management, ideal methods to assess right heart function are therefore important. LÄS MER

7. 5. Detection of paroxysmal atrial fibrillation : with special emphasis on intermittent ECG recording

   Författare :Peter Doliwa; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Atrial fibrillation (AF) is the most common sustained form of arrhythmia, affecting approximately 3 % of the adult population. AF may be symptomatic or asymptomatic. Asymptomatic paroxysmal atrial fibrillation (PAF) can be troublesome to diagnose, as most devices for arrhythmia detection provide only limited insight into heart rhythm. LÄS MER
