Vectorcardiographic Changes During Extended Space Flight. (M093)
Principal Investigator
Research Area:
Cardiovascular physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
The Skylab experiment M093 was aimed at studying changes in electrical activity of the heart during space flight. The objectives were to measure electrocardiographic changes caused by prolonged exposure to weightlessness and to assess their effects on the human cardiovascular system.
