  1. 6. Echocardiographic measurements at Takotsubo cardiomyopathy : transient left ventricular dysfunction

    Författare :Micael Waldenborg; Kent Emilsson; Ole Fröbert; Per Lindqvist; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Echocardiography; takotsubo; annulus motion; cardiac autonomic function; broken heart; diastolic; ventricular mass; concentric wall motion; Medicine; Medicin; Biomedicin; Biomedicine;

    Sammanfattning : Takotsubo cardiomyopathy (TTC) is a disease characterized by transient left ventricular (LV) dysfunction and typical wall motion abnormalities in apical parts, without obvious signs of coronary influence. Due to its elusive natural cause and the lack of clarified pathology, further studies are needed. LÄS MER

  3. 7. 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. 8. Heart and lung function - in health and disease : methodological studies in clinical physiology

    Författare :Sofia Erelund; Nina Sundström; Urban Wiklund; Sandra Arvidsson; Bengt Johansson; Carl-Johan Carlhäll; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clinical physiology; reference materials; ECG; dynamic spirometry; HRV; rheumatoid arthritis; cardiovascular disease; ischemic heart disease; Clinical Physiology; klinisk fysiologi;

    Sammanfattning : The human heart and lungs constitute an intricate and dynamic system. Various clinical physiological examinations can be used to evaluate cardio-pulmonary function and identify abnormalities. Thus, it is important to understand how normal physiology presents, to be able to identify pathological findings. LÄS MER

  5. 9. Risk factors for incident heart failure and atrial fibrillation in an elderly population : The role of cardiac conduction and heart rate variability

    Författare :Bozena Ostrowska; Carina Blomström Lundqvist; Lars Lind; Mikael Dellborg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; incident heart failure; incident atrial fibrillation; prediction of heart failure; short P-wave duration; heart rate variability.; Cardiology; Kardiologi;

    Sammanfattning : Heart failure (HF) and atrial fibrillation (AF) are epidemic diseases, frequently coexisting, sharing risk factors and conferring poor prognosis. Identification of individuals at high risk of HF and AF may enable early treatment and improve the prognosis. Reliable prediction models for daily clinical practice are lacking. LÄS MER

  7. 10. 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.
