Abstract :
A truly windows-based graphical user interface (GUI) for heart rate variability (HRV) is an easy-to-use, educational, and valuable research tool. The development of such a GUI is not a trivial endeavor. The document-view architecture of the Microsoft Visual Studio (MSVS), which is based upon the Microsoft Foundation Classes (MFC) written in C++, is utilized. A dynamic splitter-window is included to provide 4 simultaneous views. The GUI allows 720 various segment lengths. A total 270 different 4-paned views are possible, and 59 adjustable parameters are available. One view contains an interactively editable heart-rate-arousal and duration detector. The Lomb periodogram, the fast-Fourier transform (FFT), Poincarepsila plots, HRV in text format, phase-plane plots, multi-line heart-rate tachograms, and 2-minute-averaged Lomb and FFT power spectral amplitude plots are available.
