Hypothesis-generating for dual-lead QRS detection; prospective validation needed before clinical adoption.
The accurate detection of QRS wave is an important prerequisite for automated analysis of an ECG signal. For the purpose of improving the detection sensitivity and accuracy of single-lead QRS wave, this paper presents a new algorithm for dual-lead ECG QRS wave fusion detection. After QRS wave location of the original electrocardiogram (ECG) by a single-lead pre-detection, dual-lead decision algorithm determines single-lead or dual-lead fusion detection is employed. Single-lead detection directly uses the first or second lead test results, while fusion examination of dual-lead is decided by dual-lead fusion method and the lead judge rule. This algorithm involves variance, magnitude, RR intervals, template matching and the threshold comparison method and so on. Using the MIT-BIH arrhythmia database to validate the algorithm, the statistics show that an average sensitivity and accuracy are 99.87%, 99.81% respectively, which are higher than single-lead.
