Webb16 mars 2024 · Hypokalaemia causes widespread downsloping ST depression with T-wave flattening/inversion, prominent U waves and a prolonged QU interval. Right ventricular hypertrophy (RVH) Right ventricular hypertrophy (RVH) causes ST depression and T-wave inversion in the right precordial leads V1-3. Right Bundle Branch Block (RBBB) 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 ...
