WebApr 14, 2024 · LAFB masks left ventricular hypertrophy in chest leads (due to diminished R wave amplitude in leads V 5 and V 6) and overdiagnoses it in the limb leads (due to tall R wave in leads I and aVL) . S III >1.5 mV is arbitrarily considered suggestive of concomitant hypertrophy of the anterolateral wall of the left ventricle [ 1 ]. WebR wave amplitude increased as the left ventricular lateral wall moved closer to the V5 and V6 electrodes. Alterations in R wave amplitude seen with changes in left ventricular chamber size were primarily caused by radial movement of the left ventricle in relation to the chest wall. Proximity of the left ventricle to the chest wall was therefore ...
