Patients with severe sleep-disordered breathing are two to four times more likely to experience complex, abnormal heart rhythms while sleeping than individuals without the problem, according to the Sleep Heart Health Study (SHHS).
These findings appear in the April 15 issue of the American Journal of Respiratory and Critical Care Medicine, published by the American Thoracic Society.
Reena Mehra, M.D., M.S., of University Hospitals of Cleveland at Case Western Reserve University in Ohio, and seven associates compared the prevalence of arrhythmias in 228 patients with sleep-disordered breathing and 338 with no sleep disorder. The individuals in both groups participated in the SHHS, a multi-center longitudinal study of designed to determine the cardiovascular consequences of sleep-disordered breathing (SDB).

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
