1. Quality Control in ECG-based Atrial Fibrillation Screening
Abstract : This thesis comprises an introductory chapter and four papers related to quality control in ECG-based atrial fibrillation (AF) screening. Atrial fibrillation is a cardiac arrhythmia characterized by an irregular rhythm and constitutes a major risk factor for stroke. READ MORE

2. Novel Approaches to ECG-Based Modeling and Characterization of Atrial Fibrillation
Abstract : This thesis deals with signal processing algorithms for analysis of the electrocardiogram (ECG) during atrial fibrillation (AF). Such analysis can be used for diagnosing patients, and for monitoring and predicting their response to various treatment. READ MORE

3. Prognostic implications of exercise induced and ambulatory ischemia in patients with stable angina pectoris
Abstract : Results from exercise testing and ambulatory ECG registration were studied in 809 patients with stable angina pectoris; special attention was paid to signs of ischemia during both tests. Autonomic nervous system activity was investigated by measurements of heart rate variability (HRV) and catecholamines in plasma and urine. READ MORE

4. Blood pressure, blood pressure variability and myocardial ischemia : studies in patients with peripheral arterial disease and matched control subjects
Abstract : Background: Patients presenting with peripheral arterial disease (PAD) often have concomitant coronary artery disease (CAD), which is frequently asymptomatic. Ambulatory blood pressure (ABP) monitoring improves risk stratification in hypertensive patients beyond that offered by office BP(OBP) measurements. READ MORE

5. Heart rate variability in patients with stable angina pectoris
Abstract : 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. READ MORE
