Abstract

This monograph consists of a discussion of the author's experimental studies of cardiovascular function in normal infants by objective methods. He employed the phonocardiograph, electrocardiograph, Frank capsule and other physical instruments for his observations. He made individual and simultaneous records of the heart sound, electrocardiograms and fontanellar, femoral and tibial pulsations in an attempt to observe the time relations between the various phases of the respective cardiovascular activities. The data on the heart sounds of infants led him to conclude that the third heart sound, which is frequently heard in infants, occurs between the first and the second sound and is due to auricular systole. The fontanellar, femoral and tibial pulse waves were studied not only as to time relation to various phases of cardiac activity but as to configuration and variations with respect to age. The phases of the cardiac cycle, heart rate and rhythmicity and the electrocardiogram were
