Abstract :
A microcomputer-based image processing system that was developed to obtain contractile properties of single heart cells is described. Cell images were videotaped while action potentials were recorded and were digitized and processed to measure sarcomere length during cell shortening. This system makes it possible to study action potentials and their associated contractions simultaneously.
