ST depression can be either upsloping, downsloping, or horizontal.66) for the best-performing lead I. · Typically the ST-segment elevation does have a J-point elevation, which is present in our case, but it is often followed by a negative T wave i. Because much of the J wave is typically hidden inside the QRS, it may manifest as a J point elevation, a slurring of the terminal part of the QRS, or a late delta wave following the QRS. For Leads V2-V3, the following cutoffs apply: >2 mm of ST elevation in men >40. 13 There is debate about whether terminal QRS slurs and notches should be considered part of the QRS segment, as recommended by the Common Standards of Electrocardiography Working Party.叶帛鑫 -
