Electrocardiogram system

Abstract

An electrocardiogram (ECG) system includes a computing device configured to be communicatively connected to patch electrodes that are affixed to skin of a patient. The computing device includes one or more processors configured to obtain electrical signals sensed by the patch electrodes while the patch electrodes are located at actual electrode locations. The processor(s) are configured to generate initial ECG data based on the electrical signals according to assumed electrode locations on the patient that differ from the actual electrode locations. The processor(s) are configured to convert the initial ECG data to converted ECG data by determining a relationship between the assumed electrode locations and the actual electrode locations; determining voltage values for reference vectors based on the initial ECG data and the relationship; and multiplying the voltage values for the reference vectors by a set of predetermined coefficients.
