Abstract:
1. A detection method for detecting a QRS wave, comprising: providing an electrocardiogram (ECG) signal; enhancing the ECG signal to generate a processed signal, wherein the step of enhancing the ECG signal to generate the processed signal comprises: defining a first threshold value; detecting a first crest of the processed signal by using the first threshold value; defining a time period following the first crest; detecting each crest following the first crest by using the first threshold value within the time period, wherein each detected crest following the first crest is defined as a second crest when the detected crest following the first crest is higher than the first threshold value; and determining whether the QRS wave occurs between the first crest and a first trough according to the detecting results of the first crest and the second crests.
