“…Signals were digitized with a sampltng rate of 200/sec and re-recorded in digital form on computer tape at the same time. Data from these digital tapes were then archived to a master archive tape arranged to facilitate subsequent analytical steps (Harrison and Bakalar, 1976). BCG and CP from the archive tape were later selectively processed according to desired ID number by means of a specialized computer program (Harrison, 1976) for feature recognition and measurement (TRAM).…”

Ballistocardiogram and carotid pulse recordings were made on a group of healthy young men and women aged 25 – 35 years. The recordings were subjected to a newly developed procedure for feature recognition and measurement (FRAM) by digital computer. Results from the FRAM were grouped according to sex of subjects tested and inspected for statistically significant differences in mean values of the many separate items calculated. There were marked differences between the men and women in those items most closely related to initial acceleration of blood in the aorta. It was hypothesized that the hyperdynamic values from the males were indicative of intrinsic functional differences between their myocardia and that of the females.
