1. Photoplethysmographic heart and respiratory rate monitoring : instrument design and evaluation
Abstract : A new optical heart and respiratory rate monitor utilising the photoplethysmographic (PPG) signal is presented.The PPG method, first developed in the 1930s, is based on the fact that incident light to the skin surface is absorbed, scattered and reflected in tissue and blood. READ MORE

2. Primary Hyperparathyroidism : A Study of Cardiovascular Dysfunction and its Reversibility After Parathyroidectomy
Abstract : Cardiovascular risk in primary hyperparathyroidism (HPT) is controversial, and studies mainly from Europe associate HPT with increased cardiovascular morbidity and mortality. Cardiovascular morphology and function were evaluated prospectively in 31 consecutive HPT patients (mean serum calcium 2.97±0. READ MORE

3. Mineralocorticoid receptor antagonists in heart failure : exploring the gap between guideline-directed medical therapy and real-world practice
Abstract : Heart failure is the possible end-result of a variety of different diseases, where ischemic heart disease and hypertension are the most common causes in high income countries. In Sweden, heart failure has a prevalence of 2% in the adult population and rises to over 10% among people over 70 years of age. The 5-year all-cause mortality is about 50%. READ MORE

4. Optical Monitoring of Cerebral Microcirculation
Abstract : The cerebral microcirculation consists of a complex network of small blood vessels that support nerve cells with oxygen and nutrition. The blood flow and oxygen delivery in the microcirculatory blood vessels are regulated through mechanisms which may be influenced or impaired by disease or brain damage resulting from conditions such as brain tumors, traumatic brain injury or subarachnoid hemorrhage (SAH).

5. Variability of blood pressure and heart rate in borderline and mild hypertension : With special reference to spectral analysis
Abstract : The aim of this thesis was to study whether blood pressure (BP) or heart rate (HR) variability in borderline (BHT) and hypertensive (HT) subjects differs from that in normotensive (NT) subjects, and whether indices for BP and HR variability can be used in risk stratification for future hypertension. The study groups consisted of 35 NT, 29 BHT, and 34 HT middle-aged men. READ MORE
