Computer analysis and plotting of physiologic signals in cardiac muscle research.
A program (Caphys) for IMB-compatible microcomputers is described which facilitates off-line analysis of muscle physiologic signals. Caphys was written as an analysis tool for data acquired through AxoTape program (Axon Instruments). Parameters for time course and amplitude of isometric contractions and intracellularly recorded action potentials are calculated by the program. The features of Caphys include low-pass filtering and derivation of the measured signals. The programs allows also screen display and printer output of the analyzed physiological tracings. Caphys is a suitable extension for the commercially available acquisition software, making the analysis and plotting of primary physiologic data faster and more efficient.
