WebThe slow spread of the impulse will result in a slow (and abnormal) activation of the right ventricle, which yields a bizarre and prolonged QRS complex on ECG. The hallmark of right bundle branch block is QRS duration ≥0,12 seconds, large R'-wave in V1/V2 and a broad and deep S-wave in V5/V6. Figure 2 illustrates a normal ECG, a right bundle ... WebOct 14, 2016 · A normal axis is between 0° and +90°, although some authors believe that the normal axis can actually extend as far to the left as −30°.
