A Configurable Algorithm for Determining the Mean Sarcomere Length of a Cardiomyocyte By Discrete Fourier Transform

We present here a configurable algorithm for determination of mean sarcomere length in isolated cardiac cells. The algorithm is based on Discrete Fourier Transform and includes special processing of the frequency spectrum in order to get fundamental frequency more accurately. Our algorithm has been tested on raw sarcomeric data acquired from isolated cardiac cells and an example of its function is presented in this work.
