2. 1. The Resting Electrocardiogram and Risk for Cardiovascular Disease : A Population-Based Study in Middle-Aged Men with up to 32 Years of Follow-Up

   Author : Christina Ström Möller; Lars Lind; Björn Zethelius; Johan Sundström; Annika Rosengren; Uppsala universitet; []
   Keywords : Medical sciences; electrocardiogram; risk factors; epidemiology; population-based studies; cardiovascular mortality; apolipoproteins; MEDICIN OCH VÅRD;

   Abstract : The aim was to contribute to the optimal use of the resting ECG by exploring, in middle-aged and elderly men, the development and regression of ECG abnormalities; the prognostic value of the ECG for cardiovascular disease compared to conventional risk factors; and the impact of age at baseline and follow-up time for prediction of cardiovascular disease.It was based on the Uppsala Study of Adult Men cohort that was started in 1970.

4. 2. Improving diagnosis of acute coronary syndromes in an emergency setting: A machine learning approach

   Author : Michael Green; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ensemble; artificial neural network; machine learning; acute coronary syndrome; electrocardiogram; case based explanation; decision support system;

   Abstract : Acute coronary syndrome (ACS) is the biggest people killer in the western world today. Despite well trained physicians and reliable diagnostic tools, diagnosing ACS early in the emergency departments (ED) remains a challenge. READ MORE

5. 3. High-Frequency ECG in Ischemic Heart Disease

   Author : Jonas Pettersson; Avdelningen för klinisk genetik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; high-frequency QRS components; electrocardiogram; myocardial infarction; myocardial ischemia; Ischemic heart disease; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

   Abstract : Analysis of high-frequency QRS components (HF-QRS) is one of the emerging methods for increasing the diagnostic performance of the electrocardiogram (ECG). The overall objective of the thesis is to investigate whether analysis of HF-QRS has the ability to provide information about ischemic heart disease and so serve as an adjunctive diagnostic tool in several clinical situations.

6. 4. 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

7. 5. Medical and social conditions in the elderly gender and age differences : the Umeå longitudinal study

   Author : Per Olov Österlind; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Population study; elderly; diseases; social situation; drug consumption; prognostic factors; reference intervals; blood components; electrocardiogram;

   Abstract : In 1981, no representative study of the medical and social conditions among elderly persons in northern Scandinavia was performed. Nor was there such a study in a smaller Swedish town than Gothenburg. This study was initiated to fill that knowledge gap. READ MORE
