title: New software QRS detector algorithm suitable for real time applications with low signal-to-noise ratios.
abstract: A new algorithm for QRS-detection is presented; it is based on template-comparison, but unlike the cross-correlation algorithm, it involves no multiplications, and is less time-consuming and therefore suitable for real-time applications. It is demonstrated that the new algorithm performs practically as well as cross correlation, and is useful in situations where low signal to noise ratios are common.
