COMPUTER-ANALYSIS AND PLOTTING OF PHYSIOLOGICAL SIGNALS IN CARDIAC-MUSCLE RESEARCH

A program (Caphys) for IMB-compatible microcomputers is described whic h facilitates off-line analysis of muscle physiologic signals. Caphys was written as an analysis tool for data acquired through AxoTape prog ram (Axon Instruments). Parameters for time course and amplitude of is ornetric contractions and intracellularly recorded action potentials a re calculated by the program. The features of Caphys include low-pass filtering and derivation of the measured signals. The program allows a lso screen display and printer output of the analyzed physiological tr acings. Caphys is a suitable extension for the commercially available acquisition software, making the analysis and plotting of primary phys iologic data faster and more efficient.
