Evaluate R-R peak detection algorithms

[rcrowder]

A candidate is this simple method; https://github.com/tru-hy/rpeakdetect

A more advanced implementation could be; An Efficient Algorithm for Automatic Peak Detection in Noisy Periodic and Quasi-Periodic Signals http://www.mdpi.com/1999-4893/5/4/588

Or just the simpler Pan-Tompkins QRS detection algorithm as used here; https://courses.cs.washington.edu/courses/cse466/15au/labs/l9/pxc3878840.pdf

Or with a ANN frontend, as used here; http://www.scirp.org/journal/PaperInformation.aspx?paperID=4708

Or the more recent Synchrosqueezing Transform; http://arxiv.org/abs/1510.02541
