  1. 1. Myocardial electromechanical function in long QT syndrome

    Författare :Dafni Charisopoulou; Michael Y. Henein; Annika Rydberg; Anders Jonzon; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT syndrome; stress-echocardiography; left ventricular filling; mechanical dispersion; diastolic myocardial function; exercise; arrhythmia; electromechanical window; speckle-tracking echocardiography; myocardial relaxation sequence.; kardiologi; Cardiology; cardiovascular disease; hjärt- och kärlforskning;

    Sammanfattning : AIM: The aim of this thesis is to assess, in LQTS and according to genotype, the myocardial electromechanical (EM) function response to exercise, its relation to symptoms and its response to b-blocker therapy. To achieve this aim, we conducted 4 studies with the following specific objectives: i. LÄS MER

  4. 3. Myocardial Perfusion and Function: Comparative assessment by ECG, SPECT and MRI

    Författare :Eva Persson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; medicinsk instrumentering; Physiology; radiologi; radiology; tomography; medical instrumentation; Klinisk fysiologi; Clinical physics; ST-segment deviation ; myocardial ischemia ; myocardial perfusion ; MRI; CMR; MPS; ECG; SPECT; Fysiologi; Cardiovascular system; myocardial function ; Kardiovaskulära systemet;

    Sammanfattning : Evaluation of myocardial perfusion and function is important in management of patients with suspected or known coronary artery disease. This thesis focuses on the use of common diagnostic methods, myocardial perfusion single-photon emission computed tomography (MPS) and electrocardiography (ECG), to enhance and validate the diagnostic information.

  5. 4. Insights into the effect of myocardial revascularisation on electrical and mechanical cardiac function

    Författare :Ihab Ramzy Guirguis; Michael Y Henein; Stellan Mörner; Reidar Winter; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial infarction; natriuretic peptides; echocardiography; ventricular function; atrial function; surgical revascularisation; speckle tracking echocardiography; Cardiology; kardiologi;

    Sammanfattning : Background: Acute coronary syndrome is known for its effect on cardiac function and can lead to impaired segmental and even global myocardial function. Evidence exists that myocardial revascularisation whether pharmacological, interventional or surgical results in improvement of systolic and diastolic left ventricular (LV) function, particularly that of the long axis which represents the sub-endocardial function, known as the most sensitive layer to ischaemia.

  7. 5. Infarct size and myocardial function : A methodological study

    Författare :Lene Rosendahl; Jan Engvall; Thor Edvardsen; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The size of a myocardial infarction (MI) and the concurrent effect on left ventricular (LV) function are essential for decisions regarding patient care and treatment. Images produced with the late gadolinium enhancement (LGE) technique visualize the scar with high spatial resolution. LÄS MER
