In ischemia, T waves are inverted, symmetric, and mostly transient (the aberrations occur while the patient is symptomatic) (Figure 6-1). Therefore, any T-wave inversions in V 2 to V 6 are considered pathologic. In such a case and in the presence of chest pain or its equivalent, there is usually no myocardial damage, as measured

the isoelectric line represents myocardial injury or ischemia. Basic facts of the ST segment. The ST segment starts at the end of the QRS and ends at the start of the T Wave. The ST segment represents the early beginning of ventricular repolarization. The portion of the EKG tracing where the QRS ends and the ST segment begins is called the J Point.
