Abstract : Several mathematical techniques were applied to a study of respiratory sinus arrhythmia, the phenomenon by which respiration modulates heart rate in normal humans and in many animals. Data taken from human subjects was used to develop computer processing methods which are useful in simulation studies and in the interpretation of monitored heart rate from remote subjects. The investigation was divided into the following three categories: (1) the development of a mathematical model relating respiration to those variations that it causes in heart rate, (2) the use of digital filtering techniques to attenuate fluctuations in heart rate which are due to respiration, and (3) the development of methods which use only heart rate to get information about respiration.
