We present a modified delay-coordinate mapping-based QRS complex detection algorithm, suitable for hardware implementation.In the original algorithm, the phase-space portrait of an electrocardiogram signal is reconstructed in Disposables a two-dimensional plane using the method of delays.Geometrical properties of the obtained phase-space portrait are exploited for QRS complex detection.

In our solution, a bandpass filter is used for ECG signal prefiltering and an improved method for detection threshold-level calculation is utilized.We developed the algorithm on the MIT-BIH Arrhythmia Database (sensitivity of 99.82% and positive predictivity of 99.

82%) and tested it on the long-term ST database (sensitivity of 99.72% and positive predictivity of 99.37%).

Our algorithm outperforms several well-known QRS complex detection Wooden Dollhouse algorithms, including the original algorithm.
