If any of the following clinical changes are noted on a test report, additional debits should be given. Hypotension or significant BP drop during moderate level of exercise. History or development of typical angina coincident with ischemic ECG changes. Unusual or severe shortness of breath. Any of above Add +50 to mild or moderate rating

Quantitative spectral analysis of the ECG can be performed on the rest 12-lead ECG and compared to reversible ischemic changes on the perfusion scan. Preliminary studies reveal that spectral analysis of the ST segment from the J-point to the top of the T wave on the rest ECG …

Risk stratification based on the initial ED ECG also has been suggested as a way of improving ED decision making. Although the initial ECG cannot exclude AMI, stable ED patients whose initial ECG is without ischemic changes are at low risk of subsequent life-threatening complications and usually can be managed in a non-intensive-care setting.

After adjustment for ischemic heart disease, there emerged a trend of borderline significance to suggest that ischemic ECG changes were more strongly associated with elderly acute stroke/TIA patients than elderly control patients. Larger outcome study will be required to determine the significance of ischemic ECG changes following acute ...

Patients with ischemic ECG changes that persist for greater than 30 minutes (refractory unstable angina) are included in this category. ST Segment Elevation AMI: Patients with symptoms suggestive of myocardial infarction and an ECG with ST segment elevation of 1 mm or more in two contiguous leads or left bundle branch block.

c. Electrocardiogram (ECG) Changes . Electrocardiographic changes can be used to support or confirm a MI. Supporting evidence may be ischemic changes and confirmatory information may be new Q waves. • ECG manifestations of acute myocardial ischemia (in absence of left ventricular hypertrophy (LVH) and left bundle branch block (LBBB)): o ST ...

Criteria that further increase probability of ischemia: number of leads, workload at which changes occur, angle of ST slope, time to ST recovery, ventricular ectopy during recovery. Location of ECG changes does not localize area of ischemia. Age-predicted maximum heart rate (220 ( age): if 85% is not reached, test is non-diagnostic
