Abstract :
In order to investigate human cardiovascular response after exposure to various acceleration (±Gz), heart rate (HR) and heart rate variability (HRV) analyses were performed by both time and frequency domain methods on electrocardiogram data from six volunteers who participated at a study conducted at the Naval Air Warfare Center Dynamic Flight Simulator Facility. Extracted HR and HRV information were respectively processed to estimate the recovery time interval until heart rate becomes stabilized from the point of G offset, and statistical results were compared for evaluation
