Normally, the height of T wave in limb leads is usually <5 and <10 mm in any chest leads. If the height of T wave is >5 mm in limb leads and >10 mm in chest leads, it is defined as peaked T wave. WebThis leads to a significant elevation in the height of the R wave in V5/V6 and depth of the S wave in V1/V2. LVH is usually accompanied by other features on the ECG including T wave inversion and ST depression in the lateral leads (I, aVL, V5, V6). These changes are sometimes referred to as the ‘left ventricular strain pattern’.
