Genetic control of biological rhythms: Independent expression of each rhythm parameter
Life Sciences, 1995Biological rhythm whose pattern approaches a sinusoidal curve can be characterized by four parameters: Period, Mesor, Acrophase and Amplitude. Inheritance patterns of these parameters were assessed by monitoring White Blood Cell (WBC) count rhythms of C57BL/6J mice, BALB/c mice and the F1 progeny prior and after injection of Cisplatinum at either 0900,

Atrial Fibrillation — Rhythm or Rate Control
New England Journal of Medicine, 2002The human heart has a complex electrical system that ensures coordinated propulsion of blood under a variety of physiologic conditions. Remarkable effort is expended with each heartbeat to maintain sinus rhythm. Arrhythmias are a system failure — and none more so than atrial fibrillation.

[Rate control or rhythm control].
Annales de cardiologie et d'angeiologie, 2010Rhythm control or rate control are the 2 therapeutic strategies for atrial fibrillation (AF) management. Despite strong physiological and epidemiological data to support a rhythm control strategy, the results of the prospective studies, especially AFFIRM and RACE trials, did not demonstrate any superiority of a rhythm control versus a rate control ...

Controlling diurnal rhythms by light
2008 10th International Conference on Control, Automation, Robotics and Vision, 2008Life on earth is strongly affected by the day-night cycle, also known as the diurnal cycle. Due to its importance in survival, many organisms have developed an internal time keeping mechanism that goes by the name of circadian rhythm. Light plays a vital role for photosynthetic cyanobacteria and changes in the light pattern result in adaptive changes ...

Rate Control vs Rhythm Control Strategies in Atrial Fibrillation
Progress in Cardiovascular Diseases, 2005Rhythm management for atrial fibrillation is a subject of intense interest. In this review, the two main strategies for rhythm management in atrial fibrillation, the "heart rate control" strategy and the "heart rhythm control" strategy, are discussed under several headings.

The Neuroendocrine Control of Seasonal Rhythms
2000In many parts of the world, animals are exposed to large seasonal fluctuations in environmental conditions, particularly temperature and food availability. To cope with these changes, most long-lived species that spend at least part of the year in regions where annual differences in environmental conditions are very pronounced, exhibit seasonal cycles ...

Rate control versus rhythm control--decision making.
The Canadian journal of cardiology, 2007The present review examines the data and presents recommendations concerning the selection of rate-control or rhythm-control strategies, as opposed to the selection of specific therapies for rate control or rhythm control. There are several trials completed and others in progress that address issues surrounding the comparison of the two strategies ...
