System and method for ECG data classification for use in facilitating diagnosis of cardiac rhythm disorders with the aid of a digital computer
First Claim
1. A system for ECG data classification for use in facilitating diagnosis of cardiac rhythm disorders with the aid of a digital computer, comprising:
- a database to store ECG data obtained via an electrocardiography monitor comprising a patient button and an extended wear electrode patch, wherein the extended wear electrode patch comprises a backing, a pair of electrocardiographic electrodes conductively exposed on a contact surface of each end of the backing, a non-conductive receptacle adhered to an outward-facing surface of the backing and comprising a plurality of electrical pads, a battery electrically interfaced to a pair of the electrical pads on the non-conductive receptacle, and a circuit affixed on each end of the backing; and
a server comprising a central processing unit, memory, an input port to receive the ECG data from the database, and an output port, wherein the central processing unit is configured to;
identify within the ECG data at least one press of the patient button;
define within the ECG data a button window comprising a segment of data prior to and after the press of the patient button;
divide the ECG data into blocks;
apply noise detection analysis to the blocks of ECG data;
assign a classification comprising one of noise and valid data to each ECG data block based on the noise detection analysis;
identify at least one block of ECG data assigned the noise classification that overlaps the button window;
trim the at least one block of ECG data to align with one of the start and end of the button window; and
remove from the ECG data the blocks and the trimmed blocks assigned with the noise classification.

Abstract
A system and method for ECG data classification for use in facilitating diagnosis of cardiac rhythm disorders is provided. ECG data is obtained via an electrocardiography monitor with a patient button. A press of the patient button is identified within the ECG data. A button window with a segment of data prior to and after the button press is defined within the ECG data. The ECG data is divided into blocks. Noise detection analysis is applied to the data blocks. A classification of noise or valid data is assigned to each data block based on the noise detection analysis. At least one data block that overlaps the button window is assigned the noise classification. The at least one data block is trimmed to align with one of the start and end of the button window. The trimmed blocks assigned with the noise classification are removed from the data.
