我们已经开发了一个实时算法检测的QRS波群的心电信号。它基于斜率、振幅和宽度的数字分析可靠地识别QRS波群。特殊的数字带通滤波器可减少ECG信号中存在的各种类型干扰引起的错误检测。这种过滤允许使用低阈值，从而提高检测灵敏度。该算法周期性地自动调整阈值和参数，以适应QRS形态和心率等ECG变化。对于标准的24小时MIT/BIH心律失常数据库，该算法正确检测99.3%的QRS波群。
We have developed a real-time algorithm for detection of the QRS complexes of ECG signals. It reliably recognizes QRS complexes based upon digital analyses of slope, amplitude, and width. A special digital bandpass filter reduces false detections caused by the various types of interference present in ECG signals. This filtering permits use of low thresholds, thereby increasing detection sensitivity. The algorithm automatically adjusts thresholds and parameters periodically to adapt to such ECG changes as QRS morphology and heart rate. For the standard 24 h MIT/BIH arrhythmia database, this algorithm correctly detects 99.3 percent of the QRS complexes.
