WebJun 5, 2024 · A Q wave is any negative deflection that precedes an R wave The Q wave represents the normal left-to-right depolarisation of the interventricular septum Small ‘septal’ Q waves are typically seen in the left-sided leads (I, aVL, V5 and V6) Q waves in context Q … WebThe QRS may be small (or low voltage) in pericardial effusion, high BMI, emphysema, cardiomyopathy and cardiac amyloid. The QRS is tall in left ventricular hypertrophy (LVH) The criteria suggestive of LVH on the ECG is if the height of the R wave in V6 + the depth of the S wave in V1. If this value is >35mm this is suggestive of LVH.
