1. Aortic valvular flow : a clinical and experimental doppler echocardiographic study
Sammanfattning : Aortic blood velocity determination by ultrasound Doppler is a safe and valuable tool when evaluating patients with heart disease. The time-course of the velocity signal can be used for detemnining left ventricular function. LÄS MER
2. Towards Heart Rate Variability Tools in P-Health : Pervasive, Preventive, Predictive and Personalized
Sammanfattning : Heart rate variability (HRV) has received much attention lately. It has been shown that HRV can be used to monitor the autonomic nervous system and to detect autonomic dysfunction, especially vagal dysfunction. Reduced HRV is associated with several diseases and has also been suggested as a predictor of poor outcomes and sudden cardiac death. LÄS MER
3. Cardiovascular response to hyperoxemia, hemodilution and burns : a clinical and experimental study
Sammanfattning : The last decades less invasive monitoring and analytical tools have been developed for the evaluation of myocardial mechanics in clinical praxis. In critical care, these are longed-for complements to pulmonary artery catheter monitoring, additionally offering previously inaccessible information. LÄS MER
4. Exploring Polymer-Shelled Microbubbles: Detection Modeling and Application
Sammanfattning : Ultrasound imaging (US) is widely used in clinical practice. Given the low cost and easy access to the ultrasound machine, US has a great potential to improve the health care condition for the majority of the population in the world. The US could be significantly improved by injecting ultrasound contrast agents to opacify the bloodstream. LÄS MER
5. Assessment of Valvular Aortic Stenosis by Signal Analysis of the Phonocardiogram
Sammanfattning : Aortic stenosis (AS) is one of the most prevalent valvular heart diseases in elderly people. According to the recommendations of both the American Heart Association and the European Society of Cardiology, severity assessment of AS is primarily based on echocardiographic findings. LÄS MER
