Webnormal chest lead ECG shows an rS-type complex in lead V1 with a steady increase in the relative size of the R-wave toward the left chest and a decrease in the S wave amplitude. Leads V5 and V6 generally show a qR-type complex, with R-wave amplitude in V5 often taller than V6 because of the attenuating effect of the lungs. WebNote that the Q-wave must be isolated to lead III (i.e the neighbouring lead, which is aVF, must not display a pathological Q-wave). As noted above, the small r-wave in V1 is occasionally missing, which leaves a QS-complex in V1 (a QRS complex consisting of only a Q-wave is referred to as a QS-complex).
