System and method for providing dynamic gain over non-noise electrocardiographic data with the aid of a digital computer
First Claim
1. A system for providing dynamic gain over non-noise electrocardiographic data with the aid of a digital computer, comprising:
- a download station configured to execute code comprising;
a value module configured to obtain a time series of a plurality of voltage values that comprises a digital representation of a raw electrocardiography (“
ECG”
) signal recorded by an ambulatory monitor recorder;
a mark module configured to mark one or more segments of the ECG signal as noise, each of the segments comprising a plurality of the values, based on a difference between a maximum one and a minimum one of the values within that segment; and
an analysis module configured to analyze further segments not marked as noise each of the segments comprising a plurality of the values, and to determine a gain factor for all of the values in the analyzed further segments based on the analysis.

Abstract
In one embodiment, a system and method for providing dynamic gain over non-noise electrocardiographic data with the aid of a digital computer are provided. A time series of a plurality of voltage values that comprises a digital representation of a raw electrocardiography (“ECG”) signal recorded by an ambulatory monitor recorder is obtained. One or more segments of the ECG signal is marked as noise, each of the segments including a plurality of the values, based on a difference between a maximum one and a minimum one of the values within that segment. Further segments not marked as noise are analyzed, each of the segments comprising a plurality of the values. A gain factor for all of the values in the analyzed further segments is determined based on the analysis.
