Based on the analysis of deficiencies in traditional QRS complexes detection algorithm, aiming at the real-time detection requirement of mobile ECG monitoring system on ECG signal, and in combination with the characteristics of ECG curve, we propose an algorithm of composite wave filter and improved curve feature point extraction, and use adaptive threshold to implement the real-time QRS complexes detection. By testing the mobile ECG signal, it is demonstrated that this algorithm is accurate and useful, and is suitable for real-time detection and analysis of QRS complex in mobile ECG monitoring system.
