This study was undertaken with the following ends in view:
To furnish standards, so far as the available data will permit, of the average normal pulse rate under basal conditions and the extent of normal variations from this average.
To observe the changes in pulse rate with age and with sex.
To compare the age curve of pulse rate with the age curve of metabolic rate.
Data have been obtained through a survey of the published records of basal metabolism experiments, in which normal subjects were studied.
REVIEW OF THE LITERATURE
It is not our purpose to present a complete review of the literature on the subject of pulse frequency. The reader is referred to the work of Tigerstedt1 for a thorough discussion. Only a few points which appear pertinent to the subject matter of this study will be mentioned.Average normal values given by Tigerstedt are copied from
