The QRS complex is the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG or EKG). It is usually the central and most visually obvious part of the tracing. It corresponds to the depolarization of the right and left ventricles of the heart and contraction of the large ventricular muscles. WebJan 29, 2024 · QRS morphology: Narrow, normal-looking QRS shape; supraventricular origin. P waves: There is a P wave for every QRS complex and a QRS complex for every P wave, except in the region of tachycardia.

WebMonophasic QRS complex is a complex when there is only 1 wave present in a QRS complex Note:To label a negative wave as “q” or “s” we must have a “R” wave. Sometimes there is a QRS complex which does not have a positive deflection and has only a negative deflection, so we will label it as “QS” or “qs” depending upon the ...
