Abstract
Systems and methods for serial analysis of electrocardiograms are presented, wherein serial electrocardiographic (ECG) assessment is incorporated with three-dimensional vectorial analysis of the cardiac electrical signal, using changes in novel 3D-based vectorial markers over time to improve diagnostic sensitivity for acute coronary syndromes (ACS), and improve differentiation of ACS from the broad range of heart diseases that resemble ACS on ECG.
Claims6
A method for detecting a first cardiac condition, comprising:
- a. providing a first quantity of 12-lead ECG data, and at least a second quantity of 12-lead ECG data from a patient;
- b. constructing a 3-D representation of cardiac activity from the first and second quantities of ECG data;
- c. computing values for one or more parameters based upon at least one of said 3-D representation of cardiac activity from the first quantity of ECG data;
- c. computing values for said one or more parameters based upon at least one of said 3-D representation of cardiac activity from the second quantity of ECG data;
- d. calculating a difference in said one or more parameters between the first quantity of ECG data and the second quantity of ECG data;
- e. conducting an analysis of said calculated differences in said one or more parameters;
- f. forming one or more conclusions regarding the cardiac condition of a patient based upon the analysis of said calculated differences in one or more parameters;
- g. providing feedback to a healthcare provider regarding said conclusions
