A histogram and difference based approach for R wave real time detection

An efficient, very simple and new approach for real time detection of R-wave is described in this paper, which integrates histogram method and difference method with low time complexity, at the same time, the method has quite good result even when ECGs are tilted due to respiration and in the presence of power line oscillation. Experiments illustrate that this method is so robust and efficient that it had applied to digital temporary pacemaker developed by our team successfully.
