Abstract
A method has been devised for calibrating and measuring aspects of displacement records of cardiac movement. Forty-five normal subjects have been studied using this method, and a normal range has been calculated for the heights of the a wave, systolic outward movement, rapid-filling wave, and the ratio of rapid-filling wave to duration. The consistency of the results obtained and factors producing variations are discussed.Keywords
