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

    Author : Bozena Ostrowska; Carina Blomström Lundqvist; Lars Lind; Mikael Dellborg; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. The heart rate method for estimating oxygen uptake in walking and cycle commuting : Evaluations based on reproducibility and validity studies of the heart rate method and a portable metabolic system

    Author : Jane Salier Eriksson; Peter Schantz; Hans Rosdahl; Jostein Hallén; Gymnastik- och idrottshögskolan; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heart rate; Oxygen consumption; Validity; Reproducibility; Oxycon Mobile; Douglas Bag Method; Cycle commuting; Walking commuting; Medicin Teknik; Medicine Technology;

    Abstract : Walking and cycling to work can contribute to population health, but more objective knowledge concerning exercise intensities, oxygen uptake and the metabolic demands of this physical activity is needed for this and other evaluations. To attain this, valid and reliable instruments are a requirement. READ MORE

  5. 3. Spectral analysis of the heart rate variability : a methodological study

    Author : Urban Niklasson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart-rate variability; R-R interval; cardiac autonomic function; spectral analysis; IPFM model;

    Abstract : Heart rate and other cardiovascular variables are not steady but fluctuate over time. The evolution of computer technology the last 2 decades has made detailed analysis of the fluctuations possible and has focused the attention to the information content of the variability. READ MORE
