WebSmall Q waves are commonly a normal finding in the inferior leads III and aVF, and in the anterolateral leads aVL, I, V5 and V6. Q waves of 0.04 seconds (1 mm) duration and greater than one third the R wave's amplitude in the same lead may be pathological. WebTwo small septal q-waves can actually be seen in V5–V6 in Figure 10 (left hand side). An isolated and often large Q-wave is occasionally seen in lead III. The amplitude of this Q-wave typically varies with ventilation and it is therefore referred to as a respiratory Q-wave. Note that the Q-wave must be isolated to lead III (i.e the ... biological findings
