WebJun 26, 2024 · Inferior q waves on ECG indicate possible prior inferior wall myocardial infarction (heart attack). To be significant, the q wave must be at least 25% or more in amplitude compared to following r wave, and be 1 mm wide. If it does not meet these criteria, it is a “borderline” q wave, and is less likely to indicate a prior heart attack. WebQ waves. A normal ECG has only very small Q waves.
