Patent number: 10285612Abstract: When detecting ischemia and/or myocardial infarction in a subject, electrocardiogram (ECG) segments are analyzed for elevated ST segments indicative of ischemia and/or infarction. To mitigate false positive alerts, an ECG segment comprising an elevated ST segment that triggers an alert is presented to a clinician for verification as being indicative of ischemia or infarction, or as being attributable to a confounding condition not indicative of ischemia or infarction. Clinician feedback is used to adjust an elevated ST segment detection algorithm to improve accuracy and mitigate false positive alerts.Type: GrantFiled: August 31, 2015Date of Patent: May 14, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Richard E.
