WebWhat is a normal Q wave on ECG? The Q wave is the first downward deflection after the P wave and the first element in the QRS complex. When the first deflection of the QRS complex is upright, then no Q wave is present. The normal individual will have a small Q wave in many, but not all, ECG leads. WebDepolarisation of the interventricular septum is represented by Q waves on the ECG. Normally, Q waves are seen in Leads I, II, III, aVF, V5 and V6, but their duration should not be longer than 0.03 s and they should not be deeper than 5 mm in children above 3 yrs of age. In children younger than 3 yrs, Q wave amplitude of up to 8 mm can be normal. WebWolff-Parkinson-White syndrome (WPW) is characteristically diagnosed by the presence of a short PR interval, a delta wave, and a wide QRS wave on the surface ECG. In the absence of these clear criteria, absent septal Q waves have been used as additional evidence suggestive of subtle preexcitation.
