When the initial deflection of the QRS complex is negative (below the baseline), it is called a Q wave. 2. The first positive deflection in the QRS complex is called an R wave. 3. A negative deflection following the R wave is called an S wave. Thus the following QRS complex contains a Q wave, an R wave, and an S wave: In contrast, the ...

WebThe negative deflection is normally <1 mm. P-wave duration should be ≤0,12 seconds. P-wave amplitude should be <2,5 mm in the limb leads. P-pulmonale implies that the P … WebThe QRS duration is generally <0,10 seconds but must be <0,12 seconds. If QRS duration is ≥ 0,12 seconds (120 milliseconds) then the QRS complex is abnormally wide (broad). This is very common and a significant finding. The reason for …
