Q waves in v1

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). WebApr 13, 2024 · Fig. 9.1 (a) An ECG of a patient with old inferolateral infarction. There are abnormal Q waves in the inferior leads (II, III and aVF) and tall R wave (a mirror image of a Q wave) in lead V2. (b) ... T wave inversion in leads V1-V3 is often seen in children and young women and should not be confused with the Wellens’ sign.

WebThe vector is directed forward and to the right. The ventricular septum is relatively small, which is why V1 displays a small positive wave (r-wave) and V5 displays a small negative wave (q-wave). Thus, it is the same electrical vector that results in an r-wave in V1 and q-wave in V5. The third vector: the ventricular free wall WebMar 31, 2014 · Authors further concluded that QS deflections in leads V1-V2 appeared most often to be an artifact of precordial lead placement.
