1. 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
2. Towards heart rate variability tools in p-health
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
3. Heart rate variability and pacemaker treatment in children with Fontan circulation
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
4. Heart Rate Variability in Stress-related Fatigue, Adolescent Anxiety and Depression and its Connection to Lifestyle
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
5. Heart rate variability in patients with stable angina pectoris
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
