Objectives: LVH RVH PE EKG of LVH Several EKG criteria have been used in the diagnosis of LVH. These include: CHANGES IN THE PRECORDIAL LEADS Abnormalities in the QRS complex Increased amplitude or voltage of the QRS complex Limb leads R wave in any limb lead measuring ≥20 mm S wave in any limb lead measuring ≥20 mm R wave in aVL >11 mm R in lead I +S in III >25 mm Precordial leads S wave in V1 or V2 ≥30 mm R wave in V5 or V6 ≥30 mm R wave in V5 or V6 >26 mm S wave in V1, V2 or V3 ≥25 mm R wave in V4, V5 or V6 ≥25 mm SV1 + RV5 or V6 > 35 mm Tallest S + tallest R in V1 to V6 >45 mm R wave in V6 > R wave in V5 Limb + Precordial leads R wave in aVL + S wave in V3 >20 mm in females R wave in aVL + S wave in V3 >28 mm in males Total QRS voltage from all 12 ECG leads >175 mm Increased duration of the QRS complex Delayed onset of intrinsicoid deflection ≥ 0.05 seconds in V5 or V6 Increased duration of the QRS complex ≥ 0.09 seconds Abnormalities in the ST segment...
