Naming of the waves in the QRS complex is easy but frequently misunderstood. The following rules apply when naming the waves: 1. A deflection is only referred to as a waveif it passes the baseline. 2. If the first wave is negative then it is referred to as Q-wave. If the first wave is not negative, then the QRS complex does … See more The QRS complex can be classified as net positive or net negative, referring to its net direction. The QRS complex is net positive if the sum of the positive areas (above baseline) exceeds that of the negative areas (below … See more Depolarization of the ventricles generate three large vectors, which explains why the QRS complex is composed of three waves.

WebNov 22, 2024 · It is commonly mistaken as a QS complex when the R wave is very small. Qr: deep Q wave followed by a small R wave. Normal morphology in lead aVR. When found in other leads, it is a sign of myocardial infarction (previous STEMI) in the corresponding heart area. QS: a lone, deep negative wave. WebNotice that capital letters ( QRS) are used to designate waves of relatively large amplitude and small letters ( qrs) label relatively small waves. (However, no exact thresholds have been developed to say when an s wave qualifies as an S wave, for example.) The QRS naming system does seem confusing at first.
