1. Risk factors for incident heart failure and atrial fibrillation in an elderly population : The role of cardiac conduction and heart rate variability
Sammanfattning : 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. LÄS MER
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
Sammanfattning : 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. LÄS MER
3. Spectral analysis of the heart rate variability : a methodological study
Sammanfattning : 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. LÄS MER

Sammanfattning : .... LÄS MER
5. Aspects of central integrative and efferent mechanisms in cardiovascular reflex control
Sammanfattning : .... LÄS MER
