It is unclear whether STE measured at the J point or 60 milliseconds after the J point is superior when evaluating fibrinolytic or PTCA criteria. Here is an example of J point notching indicated by the blue arrow in lead II: In the same patient, same ECG, we also see notching in V5: Because these notches occur at the J point, they are sometimes also called J waves. n = 2, 3%; p < 0. 20–23 guishes early repolarization from pericardi It is two to four times more prevalent in men and three times more prevalent in African … · The diagnostic accuracy of ST-deviations was highest at +80ms after the J-point, and at 2min into recovery.
