1. Aspects on Cardiac Pumping
Sammanfattning : Cardiac pumping physiology is important for understanding the pathophysiology of patients with cardiac disease. MRI gives the opportunity to measure volumes and flow non-invasively with high accuracy and precision. This thesis examines some aspects on cardiac pumping physiology. LÄS MER
2. Right ventricular volume load and function in congenital heart defects
Sammanfattning : .... LÄS MER
3. Pump Physiology in the Remodeled Heart
Sammanfattning : This thesis aimed to increase the understanding of pump physiology in the remodeled heart compared to normal pump physiology.Study I was a cross-sectional observatory study investigating the regional contributions to stroke volume in patients with heart failure prior to cardiac resynchronization therapy (CRT) and tested the hypothesis that this characterization of pumping could predict CRT response.

4. Mitral annulus motion in left ventricular pumping
Sammanfattning : This thesis focus on the role of the mitral annulus motion (MAM) versus outer contour changes in the short axis, in left ventricular (LV) pumping. The influence of atrial contraction on LV dimensions and volumes and the relation between MAM and ejection fraction (EF) in sinus rhythm and in atrial fibrillation was also studied. LÄS MER
5. Exercise physiology and cardiac function. Aspects on determinants of maximal oxygen uptake
Sammanfattning : Although the athlete's heart has been of interest for over 100 years, further characterization of the athletes heart is needed in order to understand how training affects cardiac dimensions and function. Few studies have investigated the effects of training in female athletes and few have compared males and females. LÄS MER
