  2. 1. Ischaemic heart disease - risk assessment, diagnosis, and secondary preventive treatment in primary care : with special reference to the relevance of exercise ECG

    Author : Gunnar Nilsson; Eva Samuelsson; Thomas Mooe; Per Wändell; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise ECG; Ischaemic heart disease; Myocardial infarction; Prehospital delay; Primary care; Prognosis; Referral; Statin; Secondary prevention; Arbets-EKG; hjärtinfarkt; ischemisk hjärtsjukdom; sekundärprevention; Family Medicine; allmänmedicin;

    Abstract : Background: Ischaemic heart disease is a diagnostic and therapeutic challenge to most general practitioners. We sought to identify diagnostic characteristics and prognoses of patients in primary care that received exercise electrocardiography (ECG). We compared the ECG test results with respect to probability of subsequent cardiologist referrals. READ MORE

  4. 2. Filtering and Wavelet Regression Methods with Application to Exercise ECG

    Abstract : The analysis of the recorded electrical activity of the heart during an exercise test is a valuable method for investigating a patient's circulatory and respiratory system. But the disturbances that occurr during a test often make it difficult to interpret the signal in order to detect changes evoked by the increased workload and related to for instance coronary artery diseases.

  5. 3. Autonomic cardiac control in long QT syndrome : clinical studies of arrhythmogenic triggers

    Author : Anna Lundström; Annika Rydberg; Urban Wiklund; Håkan Eliasson; Jacob Tfelt-Hansen; Umeå universitet; []

    Abstract : Background: Long QT syndrome (LQTS) is an inherited cardiac disease characterized by prolonged cardiac repolarization and an increased risk for life-threatening arrhythmias. These arrhythmias are typically triggered by adrenergic stimuli, such as physical activity and intense emotions, implicating that the sympathetic part of the autonomic nervous system (ANS) is involved in arrhythmogenesis.

  6. 4. Diagnostic and Prognostic Value of Exercise Electrocardiographic Test Variables in Coronary Artery Disease

    Author : Håkan Kronander; Lars-Åke Brodin; Erling Löfsjögård-Nilsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; exercise ECG test; coronary artery disease; acute myocardial infarction; Medical engineering; Medicinsk teknik;

    Abstract : The diagnostic performance of conventional analysis of the exercise electrocardiographic (ECG) test for the detection of coronary artery disease (CAD) is limited to 70-75%. The exercise ECG test is the most widely used non-invasive method for assessing CAD and even a small improvement in the diagnostic performance is important. READ MORE

  7. 5. Myocardial electromechanical function in long QT syndrome

    Author : Dafni Charisopoulou; Michael Y. Henein; Annika Rydberg; Anders Jonzon; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
