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.
