  1. 1. Towards Heart Rate Variability Tools in P-Health : Pervasive, Preventive, Predictive and Personalized

    Författare :Farhad Abtahi; Kaj Lindecrantz; Birgitta Janerot Sjöberg; Fernando Seoane; Annette Bruchfeld; Metin Akay; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heart Rate Variability; Cholinergic Anti-inflammatory Pathway; Autonomic Nervous System; Vagal activity; Biofeedback; Gamification; Serious Gaming; Inflammatory Markers; Raspberry PI; Medical Technology; Medicinsk teknologi;

    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. 2. Towards heart rate variability tools in p-health

    Författare :Farhad Abtahi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Heart Rate Variability;

    Sammanfattning : Heart rate variability (HRV) has received much attention lately, and several techniques for the analysis of HRV using time and frequency domains and non-linear methods have been developed. It has been shown that HRV can be used to monitor the autonomic nervous system (ANS) and to detect autonomic dysfunction, especially vagal dysfunction. LÄS MER

  4. 3. Heart rate variability and pacemaker treatment in children with Fontan circulation

    Författare :Jenny Alenius Dahlqvist; Annika Rydberg; Urban Wiklund; Jaana Pihkala; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Congenital heart disease; Fontan circulation; heart rate variability; pacemaker; sinus node dysfunction; pediatrik; Pediatrics; kardiologi; Cardiology;

    Sammanfattning : Background: Fontan surgery is performed in children with univentricular heart defects. Arrhythmias are frequent complications, occasionally requiring pacemaker treatment. Previous data regarding indications and risk factors for pacemaker treatment in Fontan patients is limited and conflicting. LÄS MER

  5. 4. Heart Rate Variability in Stress-related Fatigue, Adolescent Anxiety and Depression and its Connection to Lifestyle

    Författare :Erik Olsson; Lennart Melin; Ulf Lundberg; Uppsala universitet; []
    Nyckelord :heart rate variability; autonomic nervous system; vagal tone; allostatic load; stress; fatigue; anxiety; depression; continuous performance; attention; cardiovascular risk; lifestyle; physical activity;

    Sammanfattning : Heart rate varies constantly as a consequence of activity in the sympathetic and parasympathetic autonomic nervous systems (SNS and PNS). In short-term recordings, heart rate variability (HRV) is mostly related to the inhibitory activity of the vagal nerves, which are part of the PNS. LÄS MER

  7. 5. Heart rate variability in patients with stable angina pectoris

    Författare :Inge Björkander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Ambulatory electrocardiographic registrations; autonomic nervous system; coronary artery disease; differential index; heart rate variability; prognosis;

    Sammanfattning : The rate and modulation of the heart beat (i.e. heart rate variability; HRV) are controlled by the autonomic nervous system. Cardiac sympathetic activation decreases and parasympathetic increases HRV. LÄS MER
