WebThe QRS also appeared a bit prolonged, and was 145 ms as measured by the computer. Subtle ST depression was seen in the inferior leads, but most concerning, a wide QRS was followed by a downsloping ST elevation in V1 and V2 that started before the J-point (AKA the sail sign) or the first five criteria below and was followed by T-inversion. WebNov 22, 2024 · ST-Segment Depression and Myocardial Ischemia. Acute ST-segment depression is, as elevation, a sign of myocardial injury.It generally correlates with incomplete coronary artery occlusion (see NSTE-ACS).As with elevation, ST-segment depression must be present in at least two adjacent leads.. It could be persistent or …
