WebA QS complex in lead V 1 is normal. A Q wave <0.03 s and <1/4 of the R wave amplitude in lead III is normal if the frontal QRS axis is between 30 and 0°. The Q wave may be normal in aVL if the frontal QRS axis is between 60 and 90°. Small septal Q waves are non pathological Q waves if <0.03 s and <1/4 of the R wave amplitude in leads I, aVL ... WebStand alone aVL T wave inversion was found in 27 ECGs (14.1%) while ischemic changes in other leads with normal aVL were identified in 36 ECGs (18.8%). The incidence of CAD was 86.3%.
