The ST segment can be normal, elevated or depressed. To be significant the S-T segment must be depressed or elevated by 1 or more millimeters in 2 consecutive limb leads or 2 or more millimeters in 2 consecutive chest leads. Look out for reciprocal changes. ST elevation indicates infarction....
Is there a relationship between any ectopy to the T wave? Step Seven: Evaluate the QT Interval Is the duration from 0.36 to 0.44 seconds? Step Eight: Evaluate other components Is the ST-segment elevated? Depressed? Sloping or scooped? Are U waves present? Prominent? Are there other (funny...

In mostcases, the first ECG shows abnormal ST segment elevation and an increase in the R wave in leads exploring the affected area (figure 94-2). Subsequently, a Q wave appears, usually while the ST segment is elevated and generally before the T wave becomes negative. Thereafter the R ...
-T wave inversion -transient ST elevation (??) -normal EKG in some cases differentiating STEMI and NSTEMI -STEMI: ST elevation in 2 contiguous leads -NSTEMI: no ST elevation, can have ST depression or T wave changes -both can show elevated cardiac enzymes ...

The early repolarization syndrome, most commonly seen in healthy young individuals, is characterized by a ST-segment elevation of 1 to 4 mm in the mid-precordial leads with a notched and elevated J point in lead V4. The precordial ECG T-wave repolarization pattern may be helpful in ...
is represented by the QRS portion of the EKG. The larger T wave which then finishes off our heartbeat is the repolarization of the ventricles. I know what you’re thinking, either “what in the what now goes where?” or hopefully, “what wave represents the repolarization of the atria”...
