1. A method, comprising:
- receiving electrocardiogram (ECG) data detected by a patient monitoring device, some of the ECG data containing a cardiac signal and some of the ECG data containing the cardiac signal and noise;
rating the ECG data based on presence or absence of both the cardiac signal and the noise, wherein rating the ECG data comprises;
rating, as a first tier, the ECG data in which the cardiac signal is present and the noise is absent;
rating, as a second tier, the ECG data in which the cardiac signal is present and the noise is present;
rating, as a third tier, the ECG data in which the cardiac signal is absent and the noise is present; and
rating, as a fourth tier, the ECG data in which the cardiac signal is absent and the noise is absent;
identifying a temporal occurrence of the ECG data and a temporal occurrence of one or more segments of noise within the ECG data, the one or more noise segments comprising one or more first noise segments and one or more second noise segments;
scrubbing the ECG data by two separate operations comprising;
filtering the one or more first noise segments that overlap with the cardiac signal; and
consolidating the ECG data to eliminate the one or more second noise segments, wherein consolidating the ECG data comprises determining a location of the one or more second noise segments relative to the cardiac signal, the one or more second noise segments rendering cardiac signal content at the location unusable for diagnostic purposes; and
generating an output comprising scrubbed ECG data, the scrubbed ECG data comprising the filtered cardiac signal and the consolidated ECG data.

Abstract
An apparatus comprises an input configured to receive electrocardiogram (ECG) data detected by a patient monitoring device, the ECG data containing a physiologic signal and one or more segments of noise within the ECG data. A scrubber comprises a plurality of scrubbing modules each configured to process the ECG data and noise in a manner differing from other scrubbing modules. The scrubber is configured to filter the one or more noise segments that overlap with the physiologic signal, and consolidate the ECG data to eliminate the one or more noise segments that are non-overlapping with the physiologic signal. An output is configured to output scrubbed ECG data.
