WebbAs the Fourth Universal Definition of MI summarizes: A QS complex in lead V 1 is normal. A Q-wave <0.03 s and <0.25 of the R wave amplitude in lead III is normal if the frontal QRS axis is between 30 o and 0 o. A Q-wave may also be normal in aVL if the frontal QRS axis is between 60 o and 90 o. WebbWhat is slurred S wave? In the normal ECG, there is a large S wave in V1 that progressively becomes smaller, to the point that almost no S wave is present in V6. A large slurred S wave is seen in leads I and V6 in the setting of a right bundle branch block. The presence or absence of the S wave does not bear major clinical significance.
