US Patent 10226631 Systems and methods for infarct detection

Systems, devices, and methods for determining occurrences of myocardial infarctions are disclosed. In one embodiment, a method of sensing for an occurrence of a myocardial infarction may include sensing a baseline accelerometer signal during a baseline, determining a baseline template based on one or more characteristics of the baseline accelerometer signal, and storing the baseline template in a memory. The method may further include sensing an accelerometer signal during a test period subsequent to the baseline, determining a test template based on one or more characteristics of the accelerometer signal during the test period, and comparing the baseline template with the test template, and based on the comparison, determining if a myocardial infarction occurred in the patient's heart. If it is determined that a myocardial infarction occurred in the patient's heart, the method may further include displaying an indication on a display that a myocardial infarction occurred.
