AUTOMATED IDENTIFICATION OF CULPRIT CORONARY ARTERY USING ANATOMICALLY ORIENTED ECG DATA DISPLAY
First Claim
1. An ECG monitoring system which identifies a culprit coronary artery associated with an acute myocardial infarction comprising:
- a set of electrodes adapted for acquisition of electrical activity of the heart from different vantage points in relation to the heart;
an ECG acquisition module coupled to the electrodes which act to produce enhanced electrode signals;
an ECG processor responsive to the electrode signals which acts to combine electrode signals for the production of a plurality of lead signals measuring electrical activity of the heart from different vantage points, wherein the ECG processor detects ST elevation in lead signals; and
a display responsive to detected. ST elevation which displays ST elevation data graphically in relation to anatomical lead locations,wherein the graphical display indicates the identity of a suspect culprit coronary artery or branch associated with an acute ischemic event.

Abstract
An ECG monitoring system analyzes ECG signals of leads associated with different anatomical locations of the body for evidence of ST elevation in the lead signals. The ST elevation and depression measurements of the leads are plotted in a graphical display organized in relation to the anatomical points which are the sources of the lead signals. The locations of the plotted measurements in the anatomically-oriented display indicate the identity of a specific coronary artery or branch as a possible culprit coronary artery for an acute ischemic event, as well as the possible severity of the event from the magnitudes of the plotted signals. A clinician can identify a suspect culprit coronary artery from a quick glance at the graphical display.

10. A method of operating an n-lead ECG monitoring system to identify a culprit coronary artery associated with an ischemic event comprising:
-
receiving ECG signals of the n-leads associated with different anatomical locations of the chest and limbs of the body; analyzing the ECG signals for ST elevation data; displaying the ST elevation data graphically in relation to anatomical locations of the body; and identifying from the graphical display a specific coronary artery or branch as a culprit coronary artery. - View Dependent Claims (11, 12, 13, 14)

15. A method of operating an n-lead ECG monitoring system to monitor the progression of a symptom of a culprit coronary artery associated with an ischemic event comprising:
-
receiving ECG signals of the n-leads associated with different anatomical locations of the chest and limbs of the body; analyzing the ECG signals for ST elevation data; displaying the ST elevation data graphically in relation to anatomical locations of the body; repeating the receiving and analyzing steps at least once at a later time; displaying the ST elevation data of the later time graphically and concurrently with the previously displayed ST elevation data; and identifying from the concurrent graphical display the progression of a symptom of coronary artery disease associated with a specifically identified coronary artery or branch.
