Validation of On-Orbit Digital Holter ECG Monitoring (JAXA_Holter)
Principal Investigator
Research Area:
Cardiovascular physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

The Holter ECG (Electrocardiograph) was developed for monitoring circadian (24-hour) cardiovascular and autonomic functions of astronauts in orbit. The ultimate goal was to understand the effects of microgravity and long-duration space flight on the cardiovascular and autonomic systems of astronauts who stay in orbit for long durations.
