Heart rate variability in type 2 diabetes mellitus: A systematic review and meta–analysis

PLoS ONE, 2018
Background Cardiac autonomic neuropathy in type 2 dibetes mellitus (T2DM) patients is frequent and associated with high cardiovascular mortality. Heart rate variability (HRV) is the gold standard to measure cardiac autonomic neuropathy.

KCS1 and VIP1, the genes encoding yeast phosphoinositol pyrophosphate synthases, are required for Ca2+‐mediated response to dimethylsulfoxide (DMSO)

FEBS Open Bio, EarlyView.
Ca2+‐mediated response to DMSO was investigated in Saccharomyces cerevisiae cells expressing Ca2+‐dependent aequorin. Cell exposure to DMSO induced a cytosolic Ca2+ wave dependent on the integrity of the Cch1/Mid1 channel. Deletion of KCS1 or VIP1 genes encoding the phosphoinositol pyrophosphate (PP‐IP) synthases suppressed the DMSO‐induced Ca2 ...

Atrial Fibrillation Detection Using RR-Intervals for Application in Photoplethysmographs [PDF]

arXiv, 2023
Atrial Fibrillation is a common form of irregular heart rhythm that can be very dangerous. Our primary goal is to analyze Atrial Fibrillation data within ECGs to develop a model based only on RR-Intervals, or the length between heart-beats, to create a real time classification model for Atrial Fibrillation to be implemented in common heart-rate ...

Determinants of short-period heart rate variability in the general population [PDF]

, 2001
Decreased heart rate variability (HRV) is associated with a worse prognosis in a variety of diseases and disorders. We evaluated the determinants of short-period HRV in a random sample of 149 middle-aged men and 137 women from the general population ...

Heart Rate Variability-Based Driver Drowsiness Detection and Its Validation With EEG

IEEE Transactions on Biomedical Engineering, 2019
Objective: Driver drowsiness detection is a key technology that can prevent fatal car accidents caused by drowsy driving. The present work proposes a driver drowsiness detection algorithm based on heart rate variability (HRV) analysis and validates the ...

Heart rate variability while assessing transplanted heart reinnervation

Инновационная медицина Кубани, 2019
Key difference of the transplanted heart is its full surgical denervation which causes features of transplanted heart physiology. Eventually a great number of studies appeared and they showed signs of innervation partial restoration and its influence on ...

Effect of meditation on scaling behavior and complexity of human heart rate variability [PDF]

arXiv, 2006
The heart beat data recorded from samples before and during meditation are analyzed using two different scaling analysis methods. These analyses revealed that mediation severely affects the long range correlation of heart beat of a normal heart. Moreover, it is found that meditation induces periodic behavior in the heart beat.

Heart Rate Variability and Pulse Rate Variability: Do Anatomical Location and Sampling Rate Matter?

Sensors
Wearable technology and neuroimaging equipment using photoplethysmography (PPG) have become increasingly popularized in recent years. Several investigations deriving pulse rate variability (PRV) from PPG have demonstrated that a slight bias exists ...

Influence of heart failure severity on heart rate variability [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2005
Introduction. Autonomic regulation of cardiovascular functions in congestive heart failure is characterised by enhanced sympathetic and diminished parasympathetic activity.
