Evaluation of Cardiac Rhythm Disturbances During Extravehicular Activity (DSO 482)
Principal Investigator
Research Area:
Cardiovascular physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
This study represents the first systematic evaluation of dysrhythmias during extravehicular activity (EVA). Twenty-four-hour electrocardiograph (ECG) tracings of Shuttle crew members (n=7) were recorded before, during and after spaceflight including EVA. A comparison of the incidence and severity of dysrhythmias across subjects and time was performed.
