WebApr 14, 2024 · Conventionally an abnormal Q wave is considered suggestive of myocardial necrosis. However, a large percentage of patients with acute myocardial infarction may not show abnormal Q waves. Electrocardiographic abnormalities may be confined to the upslope, the top, or the downslope of the R wave. WebSeptal q waves should not be confused with the pathologic Q waves of myocardial infarction. Precordial leads: (see Normal ECG) Small r-waves begin in V1 or V2 and progress in size to V5. The R-V6 is usually smaller than R-V5. In reverse, the s-waves begin in V6 or V5 and progress in size to V2. S-V1 is usually smaller than S-V2.

The QRS complex or wave starts with a small deflection downwards, represented by the point Q. It follows the P wave. After Q, there is a sharp peak, i.e. R and followed by deflection downwards, represented by S. WebDec 2, 2024 · The QRS complex has three separate Q, R and S waves.
