The Effect of Long-term Microgravity Exposure on Cardiac Autonomic Function by Analyzing 24-hours Electrocardiogram (Biological Rhythms) - 12.03.13
Science Objectives for Everyone
The Effect of Long-term Microgravity Exposure on Cardiac Autonomic Function by Analyzing 24-hours Electrocardiogram (Biological Rhythms) examines the effect of long-term microgravity exposure on cardiac autonomic function by analyzing 24-hour electrocardiogram of long-duration ISS crewmembers.

Biological Rhythms began during ISS Expedition 19/20.
- It has been demonstrated that space flight induces adverse consequences such as cardiovascular deconditioning and sleep disturbance which may be accompanied by disruption in circadian rhythms.
- As those consequences are closely related to autonomic function, cardiac autonomic function may be changed during long- term space flight.
- The objective of this study is to examine the effect of long-term microgravity exposure on cardiac autonomic function by monitoring pre; in; and post-flight 24-hours electrocardiogram.
- The results will be analyzed for improving crew health care technology in long-duration space flight.
Information PendingEarth Applications
As cardiovascular deconditioning and sleep disturbance are major adverse consequences during space flight, those problems can be seen on the earth in the people who are less fit and/or engaged in shift work. The results of this study may contribute to understanding the mechanisms of those consequences and be beneficial to manage those problems.
