测量了9种不同QRS检测算法对正常单通道II导联合成ECG的噪声灵敏度，该ECG被5种不同类型的合成噪声破坏：肌电干扰、60 Hz电源线干扰、呼吸引起的基线漂移、突然基线偏移和由所有其他噪声类型构成的复合噪声。测量检测到的QRS波群的百分比、假阳性的数量和检测延迟。没有一种算法能够在最高噪声水平下检测所有QRS波群，而不会对所有噪声类型产生任何假阳性。基于幅度和斜率的算法对于EMG污染的ECG具有最高的性能。使用数字滤波器的算法对于复合噪声破坏的数据具有最佳性能。<>
The noise sensitivities of nine different QRS detection algorithms were measured for a normal, single-channel, lead-II, synthesized ECG corrupted with five different types of synthesized noise: electromyographic interference, 60-Hz power line interference, baseline drift due to respiration, abrupt baseline shift, and a composite noise constructed from all of the other noise types. The percentage of QRS complexes detected, the number of false positives, and the detection delay were measured. None of the algorithms were able to detect all QRS complexes without any false positives for all of the noise types at the highest noise level. Algorithms based on amplitude and slope had the highest performance for EMG-corrupted ECG. An algorithm using a digital filter had the best performance for the composite-noise-corrupted data.<>
