WebbThese issues include the lead choice, U-waves, determination of the end of the T-wave, different heart rate correction formulas, arrhythmias and the definition of normal and aberrant QT intervals. Furthermore, we provide recommendations that may serve as guidance to address these complexities and which support accurate assessment of the … WebbThis satisfies the criteria of LVH. We know that the LVH pattern will often exhibit ST depression and T-wave inversion, especially in Leads I, avL, V4, V5, V6 (lateral / high-lateral leads). T-wave inversions are also present in V1, V2, V3, II, III, avF. These are consistent with and more nearly suggestive of “T-wave inversion of ischemia ...
