Claim Text:
1. A non-transitory computer-readable storage medium storing a set of instructions capable of being executed by a processor, that when executed by the processor, causes the processor to extract an electrocardiogram (ECG) signal from a signal containing noise by causing the processor to: identify putative QRS regions in the signal containing noise; cross-correlate the putative QRS regions to determine correlated QRS regions in the signal containing noise; de-noise the correlated QRS regions by filtering correlated QRS regions in the signal containing noise using a first filtering regime, wherein the correlated QRS regions are filtered by the first filtering regime in isolation of the entire signal containing noise, and filtering a remainder of the signal containing noise outside of the correlated QRS regions using a second filtering regime that is different from the first filtering regime; construct a de-noised ECG signal comprising the filtered correlated QRS regions and the filtered remainder of the signal outside of the correlated QRS regions; and present the de-noised ECG signal.
