  2. 1. Cardiovascular aspects on chronic obstructive pulmonary disease : with focus on ischemic ECG abnormalities, QT prolongation and arterial stiffness

    Author : Ulf Nilsson; Anne Lindberg; Anders Blomberg; Bengt Johansson; Christine Brulin; Per Bakke; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epidemiology; COPD; ischemic heart disease; cardiovascular disease; ECG; spirometry; kardiologi; Cardiology;

    Abstract : Background: Chronic Obstructive Pulmonary disease (COPD) is an under-diagnosed disease with a prevalence of approximately 10%, highly dependent on age and smoking habits. Comorbidities are common in COPD and of these, cardiovascular diseases (CVD) are the most common. READ MORE

  4. 2. 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

  5. 3. A Case-Based Reasoning System for the Diagnosis of Individual Sensitivity to Stress in Psychophysiology

    Author : Shahina Begum; Peter Funk; Helena Lindgren; Mälardalens högskola; []
    Keywords : Artificial Intelligence; Case-based reasoning; Sensor; Signals; Stress; Diagnosis; Computer-based system; TECHNOLOGY; TEKNIKVETENSKAP; Datavetenskap; Computer Science;

    Abstract : Increased stress is a continuing problem in our present world. Especiallynegative stress could cause serious health problems if it remainsundiagnosed/misdiagnosed and untreated. In the stress medicine, clinicians’measure blood pressure, ECG, finger temperature and breathing rate during anumber of exercises to diagnose stress-related disorders. READ MORE

  6. 4. Analysis of Electrocardiograms Using Artificial Neural Networks

    Author : Bo Hedén; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomography; radiology; Clinical physics; Lead reversal.; Myocardial infarction; Computer-assisted; Expert system; Electrocardiography; ECG-diagnosis; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : Most conventional ECG interpretation programs use decision tree logic for interpretation of the ECG. The performance is generally good but can be improved. Artificial neural networks represent a new computer method, which has proved to be of value in pattern recognition and classification tasks. READ MORE

  7. 5. Adjuncts to the Conventional 12-Lead ECG: Assessment of High-Frequency QRS Components and Additional Leads

    Author : Elin Trägårdh; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heart disease; Physiology; Fysiologi; Cardiovascular system; Kardiovaskulära systemet; myocardial infarction; 16-lead ECG; electrocardiogram; 24-lead ECG; HF-QRS;

    Abstract : The standard 12-lead electrocardiogram (ECG) is one of the most commonly used methods for diagnosing heart disease. Standard ECG is not always optimal, however, and new ECG methods can provide additional information. Analysis of high-frequency QRS components (HF-QRS) has been shown to increase the diagnostic performance of the ECG. READ MORE
