Abstract:
1. A method comprising: (a) obtaining one or more signals indicative of electrical functioning of a patient's heart, and one or more signals indicative of mechanical functioning of the patient's heart; (b) determining the patient's myocardial electrical stability by determining a degree of electrical alternans based on the one or more signals indicative of electrical functioning of the patient's heart, and determining the patient's myocardial mechanical stability by determining at least three degrees of mechanical alternans using a plurality of thresholds based on the one or more signals indicative of mechanical functioning of the patient's heart; (c) determining a myocardial electro-mechanical stability score based on the patient's myocardial electrical stability and myocardial mechanical stability; (d) determining whether the patient is at risk of an adverse cardiac event based on the myocardial electro-mechanical stability score; (e) when the patient is at risk of an adverse cardiac event, triggering a response that is specific to both the myocardial electrical stability and the myocardial mechanical stability of the patient; (f) using an algorithm to determine whether the patient's myocardium is more electrically unstable or mechanically unstable; (g) if the patient's myocardium is more electrically unstable than mechanically unstable, treating the electrical instability first, wherein treating the electrical instability first comprises using a treatment specific to the electrical instability before using a treatment specific to the mechanical instability; and (h) if the patient's myocardium is less electrically unstable than mechanically unstable, treating the mechanical instability first, wherein treating the mechanical instability first comprises using a treatment specific to the mechanical instability before using a treatment specific to the electrical instability.
