WebQ waves are sometimes seen in lead III, but disappear on deep inspiration. Q waves in leads other than the above can be considered pathological, particularly if they are: >2mV / small squares deep; or >25% of associated R wave; and/ or >0.04s; Wide or deep Q waves may indicate: Myocardial infarction; LVH; Bundle branch block

WebThe Q wave is a small negative deflection that precedes the R wave. Small Q waves (<0.03 seconds in duration) are a normal finding in all leads except V 1 through V 3, where they are always pathologic. Q waves of any size may be normal in leads III and aVR. Pathologic Q waves are indicative of transmural myocardial infarction (see Chapter 18). WebPathological Q-waves have duration ≥0,03 sec and/or amplitude ≥25% of the R-wave amplitude. Pathological Q-waves must exist in at least two anatomically contiguous leads (i.e neighbouring leads, such as aVF and III, or V4 and V5) in order to reflect an actual morphological abnormality.
