WebDoctors use the lead comparisons to determine things like axis deviations or anterior wall damage. This is part of the reason why patients might have a holter monitor, cardiac monitor, 12 lead ECG, and 15 lead ECG during the same visit. Lead 2 sets positive electrode as LL and negative as RA. Septal q waves come from the left-to-right ... WebAug 6, 2024 · A Q wave is a negative deflection before the R wave. The Q wave indicates the interventricular septum's usual left-to-right depolarization. Small 'septal' Q waves are often seen in the left-sided leads (I, aVL, V5 and V6) In most leads, little Q waves are typical. As a typical variation, deeper Q waves (>2 mm) may be found in leads III and aVR.

WebMar 11, 2024 · Q waves are inscribed when the initial QRS vector is directed away from the positive electrode. The R wave is the first positive deflection of the QRS complex; its amplitude varies by age, race, and cardiac pathology, and it should increase across the precordium from leads V1 to V5. The negative deflection after the R wave is the S wave.
