    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Co-base alloy; 35N LT; MP35N; Ta; TiN coating; electrochemical behaviour; corrosion resistance; Chemistry; Kemi;

    Sammanfattning : For patients suffering bradycardia, i.e., too slow heart rhythm, the common treatment is having a pacemaker implanted. The pacemaker system consists of the pacemaker and a pacing lead. LÄS MER

  3. 12. Echocardiographic methods for assessment of coronary artery disease

    Författare :Peter Blomstrand; Lars-Åke Brodin; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Upright bicycle exercise echocardiography with digital image acquisition in seated position during exercise and in recumbent position before and immediately after exercise was performed in 66 men, one month after an episode of unstable coronary arte1y disease. It was difficult to obtain images of adequate quality during exercise but new or worsening of wall motion abnormalities not seen in recumbent position after exercise were detected at peak-exercise in patients with good image quality.

  4. 13. Cerebral mechanisms in cardiovascular control : studies on haemorrhage and effects of sodium

    Författare :Robert Frithiof; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis describes experiments investigating the influence of the brain on cardiovascular adaptations to haemorrhage and excess sodium in conscious chronically prepared sheep. A continuous reduction in blood volume eventually activates a reflex that causes a fall in vascular resistance and heart rate and thereby also in arterial blood pressure. LÄS MER

  5. 14. Surviving Birth and Thriving : Identifying infants at risk of death and disability in low- and middle-income countries

    Författare :Antti Kukka; Ashish KC; Helena Litorp; Nick Brown; Thorkild Tylleskär; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pediatrics; neonatology; physiology; neonatal encephalopathy; hypoxia-ischemia; heart rate; neonatal resuscitation; neonatal follow-up; disabiltiy; cerebral palsy; general movements assessment; global health; low- and middle-income countries; pilot projects; telemedicine; qualitative research; Pediatrik; Pediatrics;

    Sammanfattning : Background: Ending preventable newborn deaths is an unfinished global health agenda. Infants surviving birth have a right to thrive and to reach their full developmental potential. LÄS MER

  7. 15. Aspects on early diagnosis of neonatal sepsis
