Query: Open-source software for generating electrocardiogram signals   ECGSYN, a dynamical model that faithfully reproduces the main features of the
human electrocardiogram (ECG), including heart rate variability, RR intervals
and QT intervals is presented. Details of the underlying algorithm and an
open-source software implementation in Matlab, C and Java are described. An
example of how this model will facilitate comparisons of signal processing
techniques is provided.
