Abstract

Systems and apparatus for synthesizing (generating) 12-lead ECG dataset from 3-lead ECG data. In particular, one or more transformation parameters may be determined that may be applied to 3-lead ECG dataset to generate 12-lead ECG data with particular speed and accuracy. The transformation parameters, which may include a plurality of matrices, may be determined from a synchronized patient's 12-lead ECG dataset and 3-lead ECG data. The 12-lead ECG dataset may be collected at a different time than the 3-lead ECG data. In some embodiments, the 12-lead ECG dataset and/or the 3-lead ECG dataset may be resampled prior to determining the transformation parameters.

Dependent claims

A method of generating electrocardiogram (ECG) data, the method comprising:

receiving a current 3-lead ECG data recorded from a patient, wherein the current 3-lead ECG data comprises three orthogonal or pseudo-orthogonal leads;
generating a derived 12-lead ECG dataset from the current 3-lead ECG data by applying a set of linear transformation parameters, wherein the set of linear transformation parameters are determined based at least in part on a prior 12-lead ECG dataset recorded from the patient at a first earlier collection time and a prior 3-lead ECG dataset recorded from the patient at a second earlier collection time that is different from the first earlier collection time, wherein the prior 3-lead ECG dataset is synchronized with the prior 12-lead ECG dataset by determining a representative beat for both the prior 3-lead ECG dataset and the prior 12-lead ECG dataset, wherein the set of linear transformation parameters comprises a set of transformation matrices that synthesize the prior 12-lead ECG dataset from the prior 3-lead ECG dataset, wherein the prior 3-lead ECG dataset is synchronized with the prior 12-lead ECG dataset by further resampling at least one of the prior 12-lead ECG dataset and the prior 3-lead ECG dataset;
and
outputting the derived 12-lead ECG dataset.
