  1. 11. Electrocardiographic Imaging of Myocardial Ischemia, Infarction and Scar: Correlation with SPECT, MRI and Arrhythmias

    Författare :David G Strauss; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrocardiography; Imaging; Arrhythmias; Ischemia; Infarction; Cardiomyopathy; SPECT; MRI;

    Sammanfattning : This thesis focuses on the development and testing of electrocardiographic (ECG) methods to diagnose and characterize myocardial ischemia, infarction and fibrosis (scar). The goal is to provide improved decision support to physicians regarding the optimal selection of patients for two costly, invasive therapies – percutaneous coronary intervention (PCI) for patients with acute myocardial infarction (MI) and implantable cardioverter defibrillators (ICDs) for patients with heart failure and reduced left ventricular ejection fraction (LVEF).

  3. 12. Heart rate variability in patients with stable angina pectoris

    Författare :Inge Björkander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Ambulatory electrocardiographic registrations; autonomic nervous system; coronary artery disease; differential index; heart rate variability; prognosis;

    Sammanfattning : The rate and modulation of the heart beat (i.e. heart rate variability; HRV) are controlled by the autonomic nervous system. Cardiac sympathetic activation decreases and parasympathetic increases HRV. LÄS MER

  4. 13. Left ventricular hypertrophy and the insulin resistance syndrome

    Författare :Johan Sundström; Uppsala universitet; []
    Nyckelord :Medical sciences; Left ventricular hypertrophy; insulin; glucose; lipids; mortality; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Geriatrics; geriatrik;

    Sammanfattning : Left ventricular hypertrophy (LVH) and the insulin resistance syndrome are common conditions associated with a markedly increased cardiovascular risk. In a fairly large prospective longitudinal study of men from the general population, we found that an unfavorable serum fatty acid profile and components of the insulin resistance syndrome such as dyslipidemia, obesity and hypertension at age 50 predicted the prevalence of LVH at age 70.

  5. 14. Atrial fibrillation and its association to cardiac function and structure in cardiovascular disease

    Författare :David Waldenhjort; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Aim: To study associations between atrial fibrillation (AF) and echocardiographic measures of left atrial (LA) and left ventricular (LV) parameters in patients with underlying cardiovascular disease. Hypothesis: LA and LV dysfunction can predict AF in heart failure (HF) or ischemic stroke. LÄS MER

  7. 15. Evaluation and prognostic significance of premature ventricular contractions in patients without structural heart disease

    Författare :Raffaele Scorza; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: Premature ventricular contractions (PVCs) are a common form of arrhythmia associated with poor prognosis in patients with structural heart disease. However, their prognostic impact on healthy individuals is unclear. LÄS MER
