A Mathematical Model of Respiratory Sinus Arrhythmia Using Integral Pulse Frequency Modulation

The modeling of the heart rate variability (HRV) found in the literature is most commonly based on the analysis of the interbeat time intervals in frequency domain or at discrete-time modeling. These approaches may fail if one is interested in generating the timing of the heartbeats. An alternative approach to model the HRV is the integral pulse frequency modulation (IPFM). The aim of this work...

A Mathematical Model for Flood Protection

Many regions in the world are protected against flooding by a dike, which may be either natural or artificial. We deal with a model for finding the optimal heights of such a dike in the future. It minimizes the sum of the investments costs for upgrading the dike in the future and the expected costs due to flooding. The model is highly nonlinear, nonconvex, and infinite-dimensional. Despite this...

Diminishment of Respiratory Sinus Arrhythmia

Background. The development of a microcomputer-based device permits quick, simple, and noninvasive quantification of the respiratory sinus arrhythmia (RSA) during quiet breathing. Methods and Results. We prospectively and serially measured the radionuclide left ventricular ejection fraction and the RSA amplitude in 34 cancer patients receiving up to nine monthly bolus treatments with doxorubici...
