ECG criteria are: ST segment
elevation in aVR [greater than or equal to] 1 mm, ST segment
elevation in aVR [greater than or equal to] V1, and diffuse ST segment
depression in lateral leads (subendocardial ischemia)  (Figure 2).
As noted here, pseudoinfarct pattern with ST segment
elevation or depression mimicking myocardial infarction are seen in other clinical conditions [8, 9].
Beat to beat variation of the ST segment
in a patient with right bundle branch block, persistent ST segment
elevation, and ventricular fibrillations: a case report.
Acute pericarditis can manifest with ST segment
elevation and PR segment depression on ECG (3).
* Type 2 is a saddle-back--type ST segment
elevation of [greater than or equal to] 2 mm that gradually decreases and is followed by a positive or biphasic T wave.
Cardiac biomarkers were negative and after 7 days the ECG abnormalities (horizontal ST segment
depression and T-wave inversion in inferior and lateral leads) have disappeared (Figure 4).
Among 198 patients of acute inferior wall MI, ECG performed at the time of hospitalization showed elevated ST segments
in lead V4R in 96 patients (48.5%) and elevated ST segments
in leads V3R to V6R in 80 of patients (40.9%).
Data recorded included exercise time, maximum workload, blood pressure and heart rate, diagnostic change in ST segment
, arrhythmias and reasons for stopping the stress test (limiting symptoms, ST segment
depression of > 1mm 80msec after the J point, or achievement of target heart rate).
Brugada syndrome is characterised by electrocardiographic changes demonstrating coved ST segment
elevation in the right precordial leads.
In the original report, these criteria had a low sensitivity for identifying AMI (31% and 72% for patients with discordant and concordant ST-segment elevation, respectively) but a high specificity (>90% for both concordant and discordant ST segment
The drug is an autologous adult stem cell product for the treatment of patients with left ventricular dysfunction following acute ST segment
elevation myocardial infarction (STEMI).
The syndrome of right bundle branch block, ST segment
elevation in V1 to V3 and sudden death is a clinical-electrocardiographic diagnosis based on syncopal or sudden death episodes in patients with a structurally normal heart with a characteristic electrocardiographic pattern.
