A parameter identification scheme utilizing linear programming developed by Reid and Mackay has been applied to modeling the transient heart rate response to short-term respiratory maneuvers. The method was developed specifically for identification of physiologic control mechanisms, and it is especially useful in modeling short-term transient responses due to steplike forcing functions. Parameters of linear heart rate-respiration models have been identified, and the response of the models to training data closely resembles the experimental response. This type of approach, in conjunction with empirical data of other physiologic studies, may yield important information on the mechanism and quantitative relationships involved in the dynamic heart rate response to respiration.
